Although others will disagree greatly with me for this, my experience
has taught me to just turn it off. I have burned up RAM and reached
thermal shutdown on a laptop trying to run power management. It may have
gotten better since 2.6.1, but I still don't trust it.. not after a few
hundred dollars in ram getting fried because APM didn't turn the fan on...

Generally, power management is handled by the system bios, although its
missing a few of the nifty features, the basics work.. speedstep
(assuming you're using intel), and things like that.

just my $0.02
