CPU Frequency Scaling


I am trying to get CPU Frequency Scaling to work on my Thinkpad x31. It has worked before, under both Debian and Ubuntu. I have installed the acpi-package, and cpufreqd.

After installing cpufreqd, I got the following:
Quote:
Setting up cpufreqd (2.0.0-1) ...
No cpufreq interface found, not starting cpufreqd.
I have also tried to use the CPU Frequency Scaling Monitor in Gnome, with the following result:
Quote:
CPU frequency scaling unsupported
You will not be able to modify the frequency of your machine. Your machine may be misconfigured or not have hardware support for CPU frequency scaling
I was hoping that someone here would have an answer to my problem :-)

Have you enabled it in your kernel? You need to have it compiled in your kernel (or as a module, maybe?) in order to use the feature..

I was thinking about it, but I know I didn't touch the kernel last time - so I was hoping for a solution without now aswell. Loading a module is much easier, so that might be a solution. I just don't know what module to load. Any ideas?

i'm wondering about the same thing for my debian etch install... do any of the stock kernel's (installable via apt) support cool n quiet (aka cpu freq scaling)??

I'm running an Athlon64 3000+ clocked at 2.43ghz... and i'm not real happy having it running at that speed all the time... 1. its noisy and 2. it doesn't need to run that fast! lol

i have compiled kernel's before... but i prefer not doing it... so is there an easy solution?
