If you want to use the kernel policies, look at the files 
in /sys/devices/system/cpu/cpu0/cpufreq. 

You can see which governors are available:

  $ cat scaling_available_governors
  ondemand userspace performance

Also which governor is currently active:

  $ cat scaling_governor
  performance

And of course you can change the active govenor:

  $ echo -n ondemand > scaling_governor
  $ cat scaling_governor
  ondemand

Alternatively, you can use a userspace program like cpufreqd or 
powernowd to control the frequency.  This allows much finer 
control, based on user-definable rules, battery status, a/c 
status, time, ...
