Yeah I've had problems like this a few times lately with the drm, I'm
torn between just adding select all over the place, or assuming someone
sane is configuring the kernel.

I'm sort of erring on the someone sane is configuring the kernel just
because Linus's objects to "default y" things seems to point at that we
can't really give pointers to the people who haven't done it before. So
I'm quite happy to leave it having different behaviour depending on the
configuration and simply ignoring bug reports from incompetents.
