  Log:
  Add a tunable hw.pci_disable_bios_route to work around broken PCI-BIOSes.
  
  Many BIOS implementations don't route an interrupt to cardbus bridges
  by default and some doesn't provide a working call. This results in
  panics on boot up. For the OLDCARD pcic, it was possible to force the
  interrupt-less operation, but NEWCARD doesn't have such an option and
  will never have.
