Try running powertop (yum install powertop), to see what amount of time
the processor is spending in each C-state.  The frequency scaling should
be automatic as well.   The C-7M is a strange beast, in that it  
already runs
at minimum voltage (0.798V) constantly, and it scales the frequency
continuously (since there are no corresponding voltage changes) as well.

These are applied constantly --- the automatic power management
turns on the more aggressive suspend resume using the display  
controller.
