Comment 22 for bug 355232

I also don't understand why if the module is going to be included in the kernel why it cannot have the patch to allow undervolting included. By default it does nothing except show what the current settings are. If you need to undervolt your computer (like I do because it reduces my CPU temperature drastically as I can run it at 0.9V instead of 1.5V) then you can enable it by adding the relevant scripts and settings. It is not likely to cause issues with the average user suddenly breaking their machines because they accidentally undervolted it.

The only solution for me at the moment would be to recompile the whole kernel that takes 4-5 hours or to get a precompiled kernel from someone such ad (ppa:linux-phc/ppa) where I am relying on them not to put a backdoor into my kernel (not that I think they would) and currently they do not compile for Maverick.

This is about allowing us to undervolt to run our machines cooler and not about CPU scaling. My machine already does CPU scaling and that works fine but it still runs hot because the CPU default voltages are way too high.

Please consider adding this small patch to allow undervolting.
