Fan/Power controls

[Alexander Bakst]

Hi all,

I just set up a system running a recent kernel on a G5 7,3:

[abakst@ ~/ddclient-3.7.3]$ uname -a
FreeBSD  9.0-CURRENT FreeBSD 9.0-CURRENT #314 r204309:204312M: Thu Feb 
25 09:28:38 CST 2010     
root at comporellon.tachypleus.net:/usr/obj/powerpc/usr/src/sys/GENERIC  
powerpc

I think fan controls are supposed to be enabled for this version, but my 
machine still sounds like a jet engine. Is there a way to check if 
thermal management is supported? And if it is, how do I tell it to 'go'? 
I assume that acpi and apm related documentation isn't relevant on the 
ppc platform.

Thanks,
Alexander
