Can you boot your kernel with "log_buf_len=8M drm.debug=0x14
nouveau.debug=disp=trace,i2c=trace,bios=trace" and post an updated log?

Ah, thank you.  I know what's going on here, it relates to some as of yet
unimplemented display architecture changes that GM20x requires.

I shall fix it, but it might take me a little while to figure out how exactly
to go about it.

If you build the kernel module from my tree[1], I believe your issues will be
resolved now.
