CPU Throttling

[Srikanth Konjarla]

All,

I run Fedora 8 on Tecra M5.

http://www.smolts.org/show?uuid=pub_f72f9650-72f0-4d83-9c51-0cb13856226b

It appears that the CPU throttling is not available. While, the suspend 
resume and function keys work (brightness, sound etc) wondering why the 
CPU throttling does not work and i also suspect that causes the FAN to 
run all the time. Is there a workaround or patch?

Thanks
