But you need /dev/pci in order to have something to open when you don't
have a bus number available.  (There is nothing that compels busses to
be numbered starting 0, and, if pci0 is explicitly configured but not
found, it won't exist.  Or are /dev/pci* openable even if the
corresponding bus was not actually configured?)
