Out of context, but the same issue appear with network interfaces. If
you're got 6 networks interface and the 3rd chip die, the 3 last get a
bad numbering. I am not sure it is fixable by any device.hints.

The Linux' world has the same issue (well, worse actually, as all
interfaces uses the same 'eth' name). RedHat has been/will be
introducing "Consistent Network Device Naming"[0,1] in Fedora 15,
which may be an interesting move.
