How true. In FreeBSD at least the pci cards will be found before everything
else. At least, with the old config. How this changes with the so called
new-config (just introduced into -current) I can't say, but the order of
discovery seems to be different now. What happens with PnP or pccard
controllers I can't say, since I do not have any.

At least in the existing FreeBSD framework I think my comment is valid.
And of course for older versions of FreeBSD even moreso.
