as just mentioned in another post. If you look at Ubuntu, their udev
helper that actually looks for the firmware and loads it into the kernel
does exactly this. Historically we have also old paths since the
agreement on /lib/firmware came later, but that is userspace policy
anyway and not part of the kernel.
