I really don't think we need to even "fix udev".

Why don't we just load it ourselves? Esepcially as there are probably 
places that try to avoid udev entirely, or at least use a very 
cut-down-version.

We should be fairly trivially able to be _entirely_ backwards compatible 
with any sane setup (not the _sane_ part! It implies that people don't 
copy individual modules around by hand!), with no actual breakage or need 
for distros to even update anything at all - just make the kernel able to 
look up binary blobs in the same place it installed them.

That sounds like the RightThing(tm) to do _regardless_ of any other 
issues, doesn't it? If the kernel installs it in some known place, why 
should it not just read them from that known place?
