You need to compile a kernel with BIOS fix up options enabled. The relavent 
lines in my sys/arch/i386/conf/GENERIC look like:

# Configure PCI using BIOS information
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)
#options        PCIINTR_DEBUG           # super-verbose PCI interrupt fixup

It would seem that some bioses out there are a bit lazy and do not setup the 
pci properly.
