We've had that exact discussion a few weeks ago, and I objected to
this change as there is no possible way you can know for sure people
don't use mainline with an old firmware. The whole point of the
firmware is to be an abstraction for the kernel, for better or worse.

If you really want to do something useful here, consider detecting
such firmware (even better, detect the new ones that don't require
this stuff) and document the various requirements. At least we'll know
where we stand, because the changes you're making are just as random
as what we have so far.
