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.
