You should check out the powerscope, written by Jason Flinn. Essentially its a statistical sampling profiler which accounts power (as well as time, etc). Other OS research projects have built models similar to what Arjan suggests. Ecosystem was a simple one based on state transitions, and my Koala work uses a similar model for predicting DVFS behaviour.
