It is likely that the card has an EEPROM with an OS 9 ndrv driver on it.
OS X supports these (and only these) OS 9 drivers, with some caveats
(search IOKitFundamentals for 'ndrv'). So its likely that the card works
at all because of this ndrv. Unless there really is a OS X native
IOFramebuffer for 3dfx cards, but I don't think so.
Anyway, writing an IOFramebuffer is what you'd need to do. But without
docs on the 3dfx hardware, it'd be near impossible I dare say.
