climb dramatically between 2.6.38 and 3.0.0-rc6. Currently bisecting to
find out why. .config is based on Fedora's x86_64 .config.

For the record, I am also seeing dramatically increased
CPU use with the 3.0-rc kernel, vs 2.6.38.

I first attributed it to me upgrading my video card, but
Prarit is seeing slowdowns too, so it's not just me...
