Do you need user spece tool even now?

Why not use kernel module since you have new enough kernel and it comes
with modules for it.

I have /etc/modules:
speedstep_centrino
acpi_cpufreq
cpufreq_ondemand
#cpufreq_userspace
#cpufreq_conservative
#cpufreq_powersave

Since you have AMD, you may need to use powernow-k8 instead of
speedstep_centrino.

Please google for details.

thanks for the hints

by following tutorial from http://technowizah.com/2007/01/debian-how-to-cpu-frequency-management.html i set my cpufreq to "conservative" but does this setup shuts down wireless card from time to time because my wireless connection sometimes goes on and off?

Report errors and bugs to cpufreq@lists.linux.org.uk, please.

analyzing CPU 0:

driver: powernow-k8

CPUs which need to switch frequency at the same time: 0

hardware limits: 500 MHz - 2.00 GHz

available frequency steps: 2.00 GHz, 1000 MHz, 500 MHz

available cpufreq governors: powersave, conservative, performance

current policy: frequency should be within 500 MHz and 2.00 GHz.

The governor "conservative" may decide which speed to use

within this range.

current CPU frequency is 500 MHz (asserted by call to hardware).

cpufreq stats: 2.00 GHz:32.50%, 1000 MHz:0.08%, 500 MHz:67.42% (2)
