The black screen may indeed just be due to differences between how the
2D driver treats a 8500 and a 9800, which you could get around by
commenting out the check which disables direct rendering for R300 cards
instead of overriding the chip ID. The R300 may also need a different CP
microcode though, what you experience may be the R200 microcode locking
it up. (Does the X server react to clients trying to connect, or is it
hogging the CPU maybe?)

AFAIK the R300 3D engine is completely different, so I doubt the r200 3D
driver would give any useful results even if you managed to pass the
previous hurdles.
