Correct.

We will probably need per-kernel directories, exactly like what is done for
modules. And since there are (now) both kernel-version-specific, and
non-kernel-version-specific firmware, this means the firmware loader should
look first on the version-specific directory (say, /lib/firmware/$(uname
-r)/), then if not found, on the general directory (/lib/firmware).

Nothing too dificult to pull off, but something that needs to be done before
this entire thing gets deployed on unsuspecting users. It is bad enough
that it created such a commotion when deployed on unsuspecting developers...
