Ahh, right. I didn't have the module running when I looked in
/sys/devices. Now I have it running and the fan still seems to be
working too hard. Here's what I get:
debian-powerpc:/sys/devices/temperatures# cat ./*temperature
57
59
The first should be cpu_temperature and the second gpu_temperature
debian-powerpc:/sys/devices/temperatures# cat ./*limit
50
70
The first should be cpu_limit and the second gpu_limit

What is a safe temperature for the CPU? Could I just set the cpu_limit
to 55? If so, how would I do that?
