Actually, what would be more cool is if, for those devices that
have some sort of unique data that we can look at, we `hold' the
old cloned number for that device.
E.g., I have two ethernet cards, foo3 and foo4. When I yank them
out and insert them in reverse order, they still get their original
device numbers back (because the driver recognises the MAC addresses).
When I yank one out and insert a brand new one, it gets foo5.
I don't know if this is really worth the effort, however.
