It's entirely possible to support one's government overall while disagreeing with many of the things it does. I support the US government as a whole, but I think many of it's policies concerning Iraq, Guantanamo, the "War on Drugs," immigration, etc. are despicable.
I think the same holds true for most of China's citizens. Most certainly realize that the government does bad things but this is far outweighed by the good things that it has done for the country in terms of economics development and stability.
Remember that a majority of China's population remembers a time when starvation was a very real risk and most were resigned to a future as subsistence farmer's living in a commune. Then realize that for someone who has lived through that to where China is now in terms of economic opportunity, free speech is just not that big of an issue.
Edit:
Just to clarify, I'm not suggesting that there's a necessary trade-off between economic development and free speech. My point is that most of China's population is too busy celebrating the miracle of development to care about free speech. Instead of taking for granted that economic development happened, they still remember the very real prospect that it might not have happened and still see improvement's that can be had there.
My impression is that the "nationalists" (as in blind patriotism, the word has a different meaning in Chinese) are a vocal minority among the priviledged urban youths who grew up during the economic boom. The older generations who lived through Mao's days, the less priviedged middle-class kids, and the rural population tend to have very mixed opinions.
Also, Chinese opinions tend to be very mixed to begin with, which can give off the wrong impression to someone from a society that is used to partisanism.

Because the rest of the world doesn't like free speech? Americans may throw the term around more often, but I wouldn't equate holding it important to nationalism. If anything, American nationalism has forced free speech on America, not the other way around (and yes, I'm aware of the many failures. Not saying it's perfect).
In America there is not any particular issue that is so contentious that free speech is actually curtailed. But there is tremendous social pressure for people to voluntarily curtail certain forms of speech.
If the US had a less stable society, chances are certain kinds of speech would be considered more dangerous, and we'd progress from certain forms being considered socially inappropriate to being banned outright.
This has happened in our past... and the usual framing of it is that we've progressed past such mistakes. In reality the pressures that force such things have abated.
I'd be interested to see what happened with free speech during the civil war days... I really don't know, no class has covered it and k-12 grade school has made me sick of US-history (flat-out fabrications and ridiculous exaggerations in tons of cases, and super super super dry info with few connections for the remaining). It'd be a good measuring point for this, though, as that's about as unstable as you can get. Yeah, slave-free-speech was blocked, but that's arguably mostly because they weren't really viewed as people, thus didn't have that right in the first place.
"I'd be interested to see what happened with free speech during the civil war days."
Lincoln greatly expanded the power of the Presidency in the name of War time expediency, but there were people within the Union who fiercely criticized Lincoln and his government and its policies till the very end of the war. Very different from the situation in China. (Just try criticizing the Party 60+ years after the Revolution!).
Besides, any flirtations with restrciting Freedom Of Speech lasted hardly 4 years, not half a century as in China. But then the USA had a very strong tradition of Freedom OF Speech wheras such a concept was alien to China. That said, Hong Kong seems to be relatively politically vibrant, in spite of being ruled by the MAinland. I suspect once people get used to thinking for themselves and having the freedom to express their thoughts for a generation or two, it is hard to eradicate completely.
"the full question of whether the Constitution gave the president a special power to suspend the writ of habeas corpus during wartime never got to the Court. In large part that's because the administration made sure it didn't. It had a valid fear that the Court would rule against there being such a power under the Constitution, and such a ruling would undermine the war effort. On the other hand, by keeping the matter away from the Court, the administration could largely accomplish its policy.
Opposition, especially in the press, clamored for a test case to settle whether the arbitrary arrests were legal. Secretary of War Stanton thought it would be wise to do so, too, but Attorney General Bates talked him out of it. In a letter of Jan. 31, 1863, Bates wrote to Stanton that a Supreme Court decision against the habeas corpus policy "would inflict upon the Administration a serious injury," and would do more good to the rebels "than the worst defeat our armies have yet sustained."
Bates said he would support a test case if he thought it had a chance of success. "I confess to you frankly, that, knowing as we do, the antecedents and present proclivities of the majority of that Court (and I speak of them with entire respect) I can anticipate no such results." This was after Lincoln had appointed three justices to the bench. Bates had intimate contact with the justices, and his judgment of their likely verdicts was well informed.
"Many loyal men deny this power to the President," he wrote to the Secretary of War, "and, however confident we may be that he possesses it, it is no imputation on the loyalty of the majority of the Court to presume that on this point they agree with their political school."
Lincoln certainly did unconstitutionally suspend habeas corpus. But the tens of thousands of Northern citizens who were imprisoned without due process by the Lincoln administration (as many as 38,000 by one estimate in the Columbia Law Journal) were overwhelmingly plain citizens from all walks of life who simply expressed doubt over the administration’s unconstitutional and despotic policies, including the shutting down of more than 300 opposition newspapers and the mass arrest of political dissenters by the military. Tens of thousands of Northern political prisoners spent months in a series of gulags, such as Fort Lafayette in New York Harbor, which came to be known as "the American Bastille."
I think you ask an interesting question... But it's important to consider that during the civil war the US was still largely pre-industrial and there was very little Federal power.
I think a good example of the general trend I mention is from WW2 when the US decided to set up internment camps for peaceful Americans of Japanese descent.
We did the same thing immediately after 9/11 but this time the victims were mostly immigrants who were minor immigration law violators.... but the spirit was the same.
In both cases our values go out the window the minute there is the smallest amount of pressure.
Many of the criticisms of China that I've read seem to entail that Chinese citizens are dully unaware of the benefits of free speech, or that they are hapless victims of their government. Neither is a particularly flattering picture of the Chinese as human beings... and I'd argue such criticisms amount to dehumanization and early beating of the war drums -- we never go to war against people who are our moral equals after all, and thus we must first dehumanize our enemy by reducing him to the status of a morally deficient, diminished pawn of an evil state.
From talking to people born in China that live\study in the U.S. One would predict they wouldn't support the PRC as highly on virtue of having left it and perhaps being better educated. But everyone I've met seems to.
Why don't all their high speed hackers turn against the gov, then? They have a lot of the gov's power, plus anonymity afforded by the medium of attack.
One could argue it's because of the education/brain-washing but the facts remain.
