There is soemthing screwy with the MP table presented by the BIOS
(or in our interpretation of it). Intel used to provide a programme
(mps_bchk.exe) to run under DOS to check the table and print it out. 
I will send you a copy separately. The output of that (with the -v
flag) and a dump of the PCI bus devices (/bin/pci?) would help in
analysing the problem.
