That is exactly the situation you already have with scsi disks, or
with 4 `identical' PCI ethernet cards. Being able to wire-down
a particular interface (as with scsi) would make the situation
the same as it is now, right?
(ed0 -> lan0; de0 -> lan1; el0-> lan2; de1 -> lan3)
Normal users could just let them be wildcarded; as long
as the probe sequence is deterministic, it shouldn't be
any worse to configure than currently.
