Well, as expected the EISA hacks as suggested here previously didn't
help on the mutant AIC7880 machine at work.  I've still had no luck in
getting it to probe the PCI buses correctly to find the AIC on the PCI
bus.

One suggestion was perhaps this machine has multiple primary PCI buses
and only probes one of them.  Is this something that could be fixed in
the current i386 framework?
