Flashing Success. Yet...
I finally got around to successfullly flashing the Geforce 4 that I had lying around for the G4. Sadly, although the modified Mac ROM was properly flashed onto it, it still fails to work. No video whatsoever.
Its not a really big deal since it was a cheap-ass card in the first place. I've still got some things I can do, though.

crap. whadda ya think went wrong?
