cpufreq scaling on ubuntu 12.10 (latest updates)

I have installed the modules, the libs and the scripts:
# ls /lib/modules/3.5.0-21-generic/kernel/drivers/cpufreq
cpufreq-nforce2.ko gx-suspmod.ko longhaul.ko longrun.ko
p4-clockmod.ko powernow-k6.ko powernow-k7.ko
# ls /usr/bin/*freq*
Yet, I cannot find the powernow-k8 modulefor my
amd athlon 64 3200+. Perhaps it does not exist??
If I try:
# /usr/bin/cpufreq-set -f 260000
Error setting new values. Common errors:
- Do you have proper administration rights? (super-user?)
- Is the governor you requested available and modprobed?
- Trying to set an invalid policy?
- Trying to set a specific frequency, but userspace governor is not
for example because of hardware which cannot be set to a specific
or because the userspace governor isn't loaded?
So, without powernow-k8, I cannot set cpufreq.
