That isn't true.  I just double checked, and saw my core-duo changing
between all 4 states it offers.

Yep, the ondemand governor switches between all frequencies on my
Pentium 4 M laptop.  It's a HP Pavillion dv1240us.

This governor is based on the same code as on-demand with some subtle
tweaks to make it not change the frequency as often.  If anything *this*
one should be less 'active' for you than ondemand.

I have tried the other governers (albeit a while ago) and found they
didn't manage power anywhere near as well as ondemand.  Perhaps
results vary for each governor according to CPU and chipset.
