I though powerplay was just more power states for the dpm state machines to
play with. I recall parsing ATOMBIOS pplay tables for records of (voltages/clocks
frequencies).
Maybe the future is to trust the OS kernel and perform all "low speed" 3D asic
functions there and keep only high speed 3D operations in the asic.
