anyone get cpufreq working

Anyone get CPUFREQ working to change the speed of your CPU?

When I cat the CPUFREQ file it doesn't really change anything.

echo -n "0:0:0:powersave" > /proc/cpufreq

And I get:


[root@insomnia root]# cat /proc/cpufreq
          minimum CPU frequency  -  maximum CPU frequency  -  policy


Do I need to do something else?

thanks!
