That's not how the ISA bus support works (well, worked).  Since ISA is
not an enumerable bus, we would assume that if no PCI device was claimed
by any driver then the video card must be out on ISA somewhere.

So, there's a cascade of failures here.  The PCI probe support was
broken, so the driver would (brokenly) not claim any PCI devices.  Then
the server would assume ISA, and the driver would (rightly) not find any
ISA devices.  Again: update your chips driver, the 65545 really is a PCI
device as far as I know, and newer chips drivers should have fixed the
detection bug.
