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.
