John, I thinking in terms of something like a 32 bit register (i.e. like a processor's PVR register) that has a hard-coded magic number which a driver can read and decode to determine driver compatibility. That does not sound resource-intensive given the size FPGAs we are talking about. Probably don't even need 32 bits.
