That web doc documents /lib/firmware as being the place to be. That said, there's clearly enough variation here that I think that for now I won't take the step to disable the udev part. I'll do the patch to support "direct filesystem firmware loading" using the udev default paths, and that hopefully fixes the particular case people see with media modules. We definitely want to have configurable paths and a way to configure udev entirely off for firmware (together with a lack of paths configuring the direct filesystem loading off - that way people can set things up just the way they like), but since I'm travelling tomorrow and this clearly needs more work, I'll do the first step only for now..
