Comment # 90 on bug 21273 from Ilia Mirkin

Very interesting. Note the

[   22.983172] nouveau  [     DRM] allocated 1600x1200 fb: 0x9000, bo ef220600

That means _something_ is working. I assume 1600x1200 is your monitor's
preferred resolution. What happens if you boot with the kernel command line
options "drm.debug=0xe nouveau.debug=debug"? That should provide a bunch more
info.
