hpet timer patch for powertop

[Ahmed Kamal]

actually I'm still on FC6, and I'm using i686 CPU. The kernel is from
tuxonice (suspend2) which is basically the same fedora kernel with suspend2
patches. Anyway, I thought all .22 kernels had tickless, dont they.
If all of this + hpet patches will be in fedora8, I will be a happy fedorian
;)
