: 
: options         PCIBIOS                 # PCI BIOS support
: options         PCIBIOSVERBOSE          # PCI BIOS verbose info
: options         PCIBIOS_ADDR_FIXUP      # fixup PCI I/O addresses
: options         PCIBIOS_BUS_FIXUP       # fixup PCI bus numbering
: options         PCIBIOS_INTR_FIXUP      # fixup PCI interrupt routing
: options         PCIBIOS_IRQS_HINT=0x0a00 # PCI interrupts hint. IRQ 9 or 11
: options         PCIBIOS_INTR_GUESS      # see pcibios(4)

Many of these are rolled up into FreeBSD's code already.  I'm working
on not needing addr_fixup.  bus_fixup is needed.  The intr stuff is
being worked on by John Baldwin.  The bus_fixup stuff is needed by a
few laptops now to get cardbus working...
