Correct me if I'm wrong, but doesn't this also affect those
distributions that consider kernels with binary firmware blobs to not
be free software?  Those distributions take the stance that the
firmware must be loadable by userland, in which case the proposed
patch removes this capability.

Is there some downside to leaving this functionality in there?  Are
there known bugs or maintainability issues with the code as-is?
