As you already mentioned fwpostfix: can the driver somehow do something like
the soname is for libraries, e.g. increasing a serial number in the firmware
file names? This would make it possible to install several incompatible
versions in parallel.
Example: fwcutter unpacks such versions to
/lib/modules/firmware/b43.${ABIVERSION}
and the driver looks in the directories for whatever kinds of ABIVERSION are
supported by that version of the driver.
