This was the distinction I got from reading the Apple KB. (The PMU99's I
think started to show up in later Sawtooth G4's, as indicated by the green
light / blue light difference on the power button. Apple says the PMU is
diffrent (and not a CUDA, but something else that I can't remember) and is
in a physically different location on the logic board)
