I think everything except the epia. I wish I could point you at a simple port.

Possibly an extra nesting level in Config.lb.  If you have a PCI slot
you can still have multiple busses.

Hmm. I suspect your configuration would look something like:

Except that some of the unused parts don't compile out it really
should be fairly simple.

chip northbridge/intel/440bx 
        device pci_domain 0 on 
                device pci 0.0 on end  # memory controller
                device pci 0.1 on end  # PCI-PCI bridge?
                chip southbridge/intel/piix4e
                        device pci 12.0 on end # ISA bridge
                        device pci 12.1 on end # IDE controller
                        device pci 12.2 on end # USB host controller
                        device pci 12.3 on end # Power management registers
                end
        end
        device apic_cluster 0 on
                chip cpu/intel/slot_2
                     device apic 0 on end
                end
        end
end
