I am a gentoo user an compile a lot of things. I also use freq scaling with my Athlon XP on nforce2 with cpu disconnect enabled.
idle at ~1400MHz: ~135 WATT used by system full load at ~1400MHz: ~150 WATT full load at ~2200MHz: ~230 WATT
So, if I don't need something very quickly, so can guess that I prefer to do compiling at low clock speeds... (Suspend won't work for me.)
