Nothing, you just have to enable some of the PCIBIOS options :-)

options         PCIBIOS                 # PCI BIOS support
options         PCIBIOSVERBOSE          # PCI BIOS verbose info
options         PCIBIOS_INTR_FIXUP      # fixup PCI interrupt routing
options         PCIBIOS_BUS_FIXUP       # fixup PCI bus numbering

In particular, you must have PCIBIOS and PCIBIOS_BUS_FIXUP in order
to make that problem go away.

You probably want PCIBIOS_INTR_FIXUP, too.
