Modified files:
sys/i386/include pci_cfgreg.h
sys/i386/pci pci_bus.c pci_cfgreg.c
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.
