The issue is the same with the G3 tower - the video card is by default in
the 32-bit, 66 MHz PCI slot, which is a logically separate bus from the
64-bit, 33 MHz bus that the other 3 slots are part of. What sort of mods
will it take to make that work, anyway?

I've discovered that putting both cards in bus 0 (64-bit, 33 MHz bus) gets
both the cards going, though - and well, that works for me...
