  SVN rev 190386 on 2009-03-24 18:10:22Z by jhb
  
  Fall back to using configuration type 1 accesses for PCI config requests if
  the requested PCI bus falls outside of the bus range given in the ACPI
  MCFG table.  Several BIOSes seem to not include all of the PCI busses in
  systems in their MCFG tables.  It maybe that the BIOS is simply buggy and
  does support all the busses, but it is more conservative to just fall back
  to the old method unless it is certain that memory accesses will work.
