So basically, it's not a BIOS at all. :)

Bingo. Some people have gotten 3dfx cards working to some degree on
powerpc, but I don't remember if that was only a matter of configuration
or patching code, and even in the former case, development in the
meantime could have broken powerpc support again.

That's true in general, but IIRC 3dfx cards are of the rare kind which
may actually be initialized from scratch without help from the firmware
on the proper phase of the moon. YMMV.
