Debian CPU scaling not working

[Vrekk]

In order to save power and to cool down my Debian system a little bit, I installed cpufregs the other day and changed it the cpu gonever to on_demand.

Well I came back to the box today and powertop tells me that the cpu has been running at 2.66ghz (max freq) for 99/99% of the time.

Running cpufreq says this:

analyzing CPU 0:
  driver: p4-clockmod
  CPUs which need to switch frequency at the same time: 1
  hardware limits: 333 MHz - 2.67 GHz
  available frequency steps: 333 MHz, 667 MHz, 1000 MHz, 1.33 GHz, 1.67 GHz, 2.00 GHz, 2.33 GHz, 2.67 GHz
  available cpufreq governors: ondemand, userspace, conservative, powersave, performance
  current policy: frequency should be within 2.67 GHz and 2.67 GHz.
                  The governor "ondemand" may decide which speed to use
                  within this range.
  current CPU frequency is 2.67 GHz.
  cpufreq stats: 333 MHz:0.01%, 667 MHz:0.00%, 1000 MHz:0.00%, 1.33 GHz:0.00%, 1.67 GHz:0.00%, 2.00 GHz:0.00%, 2.33 GHz:0.00%, 2.67 GHz:99.98%  (3)

For some reason or another the computer decided that the freq needs to say bewteen the max and the max , and I have no idea how to change it so that it will scale down to 333MHz.

Any ideas?

Have you tried to use conservative instead?
