Mine too, but it runs very hot and gets significantly less battery on Linux than Windows. (How you know something's wrong.)

I tried a fix or two as suggested, but they didn't help; I hope the kernel upgrade does it!

I don't know how mine compares to Windows, but it doesn't run particularly hot. I don't use anything fancy on my Linux boxes; xmonad and some terminals on my home machine, xmonad and GNOME on my work machine. Very low-CPU :)
