Heh. 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..
