I'm quite certain, that nouveau does not support the 9xx series for now, except
modesettings and the "gen7_update_renderbuffer_surface" points to an error with
the intel driver. You have an so called optimus/prime system with two cards,
intel and nvidia. Please sort out which card you are actually using.

You are correct, I was using the Intel GPU, not the nVidia one like I had
assumed. I suppose this ticket should be re-assigned, but I don't know the
