It is still slightly more “complicated” from a distribution perspective,
but if that is what makes it a “clean” solution, then that is the way to
go forward.

I will investigate the fine details, but I fear we may need some
“compatibility” magic similar to “new_id” in USB to make it work,
because it seems as if you can ONLY force a driver to bind if it
_is_ compatible...

But from what I can tell this functionality (mentioned in this article
by Greg) has not been moved into driver-core and bus, so we would need
to run our own version of it.
