Hello!
Looks like the user space cpufreq does not get registered:

Found 1 cpu.
Error writing file governor: Invalid argument
Couldn't get per-cpu data: Illegal seek
PowerNowd encountered and error and could not start.
Please make sure that:
- You are running a v2.5/v2.6 kernel or later
- That you have sysfs mounted /sys
- That you have the core cpufreq and cpufreq-userspace
modules loaded into your kernel
- That you have the cpufreq driver for your cpu loaded,
and that it works. (check dmesg for errors)
If all of the above are true, and you still have problems,
please email the author: clemej@xxxxxxxxxxxx
Any hints? I am compiling 2.6.4 right now, but I don't see changes,
which could fix this problem.
Greetings,
Nico
