Well that's kinda the problem. If you don't expect the kernel to clash
with whatever mesa is using internally then we should add it to the
kernel, first. That's kinda what Dave's recent rant has all been about.

The other issue was that originally the idea behind fourcc was to have one
formate namespace shared between drm, v4l and whomever else cares. If
people are happy to drop that idea on the floor I won't shed a single
tear.

In the end I'll expect that someone will make a funny collision between
all the different projects anyway, so meh.
