Quite frankly, I doubt that anybody will ever care, plus getting me to
care about some vendor that ships external binary-only modules is
going to be hard as hell.

Plus quite frankly, signing random kernel vendor modules (indirectly)
with a MS key is f*cking stupid to begin with.

In other words, I really don't see why we should bend over backwards,
when there really is no reason to. It's adding stupid code to the
kernel only to encourage stupidities in other people.

Seriously, if somebody wants to make a binary module for Fedora 18 or
whatever, they should go to Red Hat and ask whether RH is willing to
sign their key. And the whole "no, we only think it makes sense to
trust MS keys" argument is so f*cking stupid that if somebody really
brings that up, I can only throw my hands up and say "whatever".

In other words, none of this makes me think that we should do stupid
things just to perpetuate the stupidity. And I don't believe in the
argument to begin with.

Besides, let's face it, Red Hat is going to sign the official nVidia
and AMD binary modules anyway. Don't even bother to pretend anything
else.
