Support has been directly in the kernel for years.
On my grandma's computer I just added:
To /etc/modules to load the needed modules and correct governor. You
would have to replace the "powernow_k8" with the one for your p3.
On my laptop I installed cpufrequtils
and that made things easier and I didn't have to mess with the
/etc/modules file. I also installed klaptopdaemon for a nice gui
interface with an icon in the task tray. For klaptopdaemon to work you
have to have all the modules loaded or install it along with
cpufrequtils to take care of automatically loading the modules.
