What card is this?  This looks *very* wrong.  That "i960 RM PCI-PCI"
is not really a bus bridge, it's a CPU, generally used on RAID adapters,
that has an integral PCI bridge.  This looks like a RAID card whose
BIOS has failed to run for some reason, leaving it uninitialized.

Also, I find the double-probe of the 21154 bridge used on the
MegaRAID adapter extremely odd.  I think there is something deeply
wrong between this host's BIOS and our PCI code.  Can you try an ACPI
kernel?
