That's ... not particularly helpful. Presumably non-upstream and the
fact that it's ancient are turn-offs. Either way, he seems to have a
desire to try to get nouveau going.

I don't think I've seen this before. The odd thing about the TK1 (and
TX1, I believe), is that the GK20A device doesn't have any display
capabilities - those are left up to tegra. Sounds like you're trying
to use the nouveau ddx as the primary, which fails as there are no
CRTC's. I believe Gnurou's xserver hacks rely on you using glamor (and
thus the modesetting xorg ddx). Is that what you're using? Can you
provide an xorg log?
