Hello Joe,
The good news is that your processor should feature AMDs powernow technology,
if it does you can scale the CPUs frequency and voltage back by adjusting the
hw.setperf sysctl (takes an integer value between 0 and 100 and adjusts the
fid/vid to the closest pair compatible with your processor). With a dmesg
form a newer snapshot you can identify support for this feature by looking for
e.g.
cpu0: AMD Powernow FID VID
There are other flags FID and VID are the ones your interested in.
The bad news is that some of the early systems have a bug that prevents powernow
from being detected there is a dirty hack that can deal with this I suspect it
is
what you need rather then repost this rather verbose thread I will
direct your attention too

hmmm ... just spotted another bug in powernow-k7.c
/* On bootup the frequency should be at it's max */ is wrong true for desktop
processors "Cool n' Quiet" but not the mobile ones "Powernow" thats how you
tell them apart in any case there are more than a few people who reported that
thread as helpful so give it a shot.
Anyway hope this was helpful,
GWK
