2.6.24ish was known to be problematic for IPIs, causing lots
of wakeups.

What _I_ would do in this case (and you may choose to do the same)
would be

linux-2.6.25-rc6.tar.bz2 (or newer)
cp /boot/config-... linux-2.6.25-rc6/.config
make oldconfig
make-kpkg --initrd kernel_image
and install a hopefully nicely working 2.6.25-rc6 with a configuration
that's _fully_ compatible to your current kernel thanks to oldconfig.

Distro change? Laughable ;)
