So I finally got back to another machine to check, and this registry
entry exists on a G4 Cube w/ DVD which doesn't have the decoder card.
I think that the ATIRage128DVDDriver is just support for DVD
acceleration on Rage128 cards (the next key in the registry is an
IOMatchCategory with a String value of IOAccelerator).

Right, it is kernel-support for the DVD-framekwork, but not
specifically for ppl with the dvd decoder card, which is even better.
I think it's certainly possible, but not sure how difficult it will
