Many distribution have some way for separate kernel module packages.
It's essentially the same problem so it should be already solved
in some way. Also there are already drivers who rely on separate
firmware so they already should have this problem (and hopefully
a solution). Of course these existing solutions might not be good
enough. And a lot of people ignored them because they didn't use
these external packages and drivers with those requirements.

I agree with you that doing this for more drivers will be a further complication
and the rationale why this complication is needed for drivers like tg3 or
e100 so far didn't  sound very convincing to me. If I read it correctly it
was "some other drivers do it this way so let's complicate everybody and
put them on the same level". Perhaps I'm dense, but I failed
to see the convincing reason in that.

On the other hand for my personal use it this change should be
transparent, at least as long as "make firmware_install"
will be integrated into "make modules_install" and put the files somewhere where
they don't conflict with other versions.
