Well, all the code is still there, so it can be enabled if anyone wants it.

I think the only use (if any) of a userspace firmware loader would be
for anyone who wants a custom one (i.e., not udev), so we shouldn't
just fail the loading from udev unconditionally.

How about we just improve the udev documentation a bit, similar to
Andy's kernel patch?

Cheers,

Tom
