Are there actually any PCI cards in either of the other two busses (32-bit and 64-bit PCI bus)? I have seen this before, with the AMI BIOS, where the BIOS does not configure PCI-PCI bridges if there is nothing on the other side of the PCI bridge (or nothing but a PCI-PCI bridge, with nothing on the other side of that). This (empty PCI busses) would also make sense, given that there are no interrupt mappings in the MP table for the other PCI busses. Can you plug in a couple extra cards (at least one in each of the other two busses) and try it again? If it still doesn't work, I'll be glad to look at it, but my guess is that the multiple host-PCI bridges are implemented similarly to the 450GX chipset, and AGP in the 440BX, so it will "just work" once the BIOS configures the bridges.
