Yeah; I also suspect that this is a broken fallback path in our BGNone
patch. Intel doesn't appear to own the framebuffer before X, so the
framebuffer copy fails - something that doesn't otherwise happen - and
the server scratch pixmap state doesn't get set up.
However, I couldn't easily see why it *wasn't* getting set up. Although
I don't have a hybrid system I'll try making the framebuffer copy fail
on my system to see if I can reproduce.
