The whole "let's add a new magical proc entry to say that all
filesystems are mounted" is all about the user space coupling them.

I'm just saying that if user space must know about when firmware is
ready to be loaded anyway, just do it rigth. Not with some hacky "you
can now do random things" flag. But by having user space actually say
"put this module together with this firmware".

If you just put the two pieces together, then the module "will just work".

And quite frankly, that sounds like a much better maintenance practice
anyway. If some module doesn't work without the firmware, then dammit,
the two *should* go together. Putting them in two different places
would be *INSANE*.
