0001691: Add Frequency scaling to kernel
It would be nice for the firewall to throttle down a little bit when not under load. This would save power, cut heat etc. During off hours (night) is an example.

Ultimately add something to the GUI for what cpufreq governer you want the system to use such as ondemand, performance, conservative, etc. Otherwise let the more advanced users change it via root.
Probably need to do the drivers as modules so there is no complaints via Intel or AMD procs using the wrong driver under Power Management | CPU Frequency Scaling.
No tags attached.

Petr. That worked on an Intel based one. When I put in the ticket I have and currently using AMD based. Looks like p4_clockmod is present, however the AMD ones (powernow_k8,k7) are not.

powernow_k8 module is present in 2.4.1 community. My Opterons are now running at 1000Mhz at idle instead of the 2200Mhz they would run at full.
