Regarding #1, it's not necessarily a kernel problem. One bloated program running in the background could be using a bit too much CPU and disk. "Modern" desktop environments love those programs, for some reason.

It could be a lack of support for a specific advanced power-saving feature at kernel level, but that wouldn't be my first guess..
