  Log:
  Detect a certain type of PCIBIOS brain damage.  For some reason,
  some bios vendors took it apon themselves to "censor" the
  host->pci bridges from PCIBIOS callers, even when the caller
  explicitly asks for them.  This includes certain Compaq machines
  (eg: DL360) and some laptops.
  
  If we detect this, shut down pcibios and revert to using IO
  port bashing.
  
  Under -current, apcica does a better job anyway.
