How does this bring us closer to unifying PCI and CardBus?
Also, this seems kind of bad for e.g. ports that don't use the
kernel's PCI configuration code (relying on system firmware to do it,
instead). And, you can't really, at the system level, blindly set
PCI_CONF_ENABLE_ROM anyway, because of the broken PCI device problem.
