We definitely need conflict check code 
that covers all bus types ...
(And I have part of that ready.)

But the BusLogic would still be double
probed, I suppose, since it responds to
0x330 ISA probes but doesn't announce 
that port range as active to the PCI 
driver. This is a very bad thing, and 
the card seems to severely violate the 
PCI specs ...
