Latest Power Management tool for AMD64

[T o n g <mlist4suntong@yahoo.com>]

Hi,

My CPU is AMD 64. What's the latest and easiest power management tool for 
AMD64?

powernowd is less complicated than cpufreqd or cpudyn, but I also heard 
sayings that the 2.6 kernel ondemand cpufreq governor might be even more 
simpler, and there are many other tools like acpid, powersaved, powertop, 
etc, etc.

CPU power management has always been a problem to me, I never get it 
worked before for my desktop PC. Any hint or points to detailed 
explanations/steps is appreciated. 

thanks
