If you don't run cpuspeed and use the in kernel governors you can
choose the different governor you want to use to control your speed,
or a static speed from the applet.  This is the behavior by default on
newer cpu's, but for some reason the cpuspeed damon is still used on
older processors.  I have some scripts that load these modules for
older cpu's if anyone is interested.

This whole process is being re-architected right now.  This should all
change, hopefully in time for F9.
