powernow does not work [solved]

Hello,

powernow does not work at my notebook (AMD mobile-XP 2600+).
I tried to compile the modules (freq-table, powernow-k7) in the kernel but this did not help. I even do not get any error messages. What is wrong?
Booting a Debian-based Live-CD works fine.

What are you using to control it? You need something like one of the cpufreq kernel modules, or perhaps something in userspace like powernowd + the userspace governor. If you've already tried something like this, what happened?

Have you tried to run modprope powernow-k7?

cpufreq-info only displays "no or unknown cpufreq driver is active on this CPU"
The directory where to copy the governor does not exist! (I found the path to this directory somewhere else here in the forum.)

modprobe powernow-k7 does not show the steps as mentioned here in other threads, I now compiled the module into the kernel (and also the governors).

Has nobody any idea?

I installed Gentoo on my AMD64-desktop and it works fine (kernel 2.6.13-gentoo-r2).

I get the following message at boot:

"powernow: PowerNOW! Technology present. Can scale: frequency and voltage."

I solved the problem:

I simply updated to kernel 2.6.13-gentoo-r2
