I didn't just assume it. I checked the major distributions -- and they
_do_ check the MODULE_FIRMWARE() tags in the modules they include, and
include the corresponding firmware. The firmware loader has been around
for a _long_ time now, and they've had to support this for almost as
long.

Yes, there are occasional bugs -- and I'm sure there _are_ some minor
distributions or 'image creators' out there which still don't cope.

But that isn't a new problem -- and it's certainly not _caused_ by us
updating a small handful of the older drivers to match what modern
drivers do.
