So one might consider doing something like

find /lib/modules/`uname -r` -type d -name cpufreq | xargs ls

and do figure out and load an appropriate Linux 2.6 kernel module
to make *less* unused CPU cycles happen.

Something like

echo ondemand >/sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

and/or cpufreqd/powersaved does help, too.

E.g. my home Athlon64 3700+ sits at 1000 (with max 2200) MHz 
right now.  It's still more than enough given virtually no load.
