I have the same problem but my server is Dell PowerEdge
model 4400 with two PentiumIII, 512 RAM, 7899 with two
80 pin hard disks, a 7880 with cdrom. These chips are
built in mainboard.

I dont know about the internals of the kernel and drivers
but I feel the solution could be the same for both servers.

Please take a look to my dmesg listing and see the skip
of bus1 to bus6.
