You can't use 2 cards which require ISA IO (vgaHW uses ISA IO on rage128)
right now, because of the multiple busses on the G4 machines.  You can
comment out all the vgaHW calls and that will probably work, but without
doing that it will always crash on any ISA IO operation.  The reason is
because your second bus's ISA IO isn't mapped.
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...
