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.
