Should I expect nouveau on 4.6 to work on a GM206?

[Andy Lutomirski]

I have the signed firmware (I think) and I'm running a fresh 4.6
kernel.  I got an image to show up briefly, rendering the Fedora
sign-in screen at something like one frame per ten seconds.  But then
I got all kinds of garbage, and I see:
