Fan/Power controls

Sat Feb 27 21:28:50 UTC 2010

(Switched my non-work e-mail)

Well, I actually am using a fancy apple G5 - I belive it is a power 
970fx, not sure though. I'm not even sure how to check the current clock 
frequency of my cpu. To be honest, it would be fantastic if it weren't 
running at the highest speed, since I would like to save power. I don't 
know if the kernel will tell the cpu to snooze/nap.

Thanks,
Alexander
