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
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
