Public bug reported:

This issue prevents installing Ubuntu and booting with certain GPUs
until the Nvidia-367 graphics drivers have been installed.

Nouveau in 16.04 doesn't include support for the current series of
Nvidia GPUs (Pascal architecture, GTX 1070 and 1080), but still tries to
load, resulting in boot hanging at a blank screen.  The current behavior
will cause Ubuntu 16.04 to be difficult for most users to install on
computers with NVidia hardware newer than the previous generation.

To reproduce:
Create an Ubuntu live image and attempt to install Ubuntu on a computer with an 
NVidia Pascal GPU.

Expected Results: Ubuntu graphical installer appears.
Actual Results: Boot hangs at blank screen.

Possible fix: 
https://github.com/skeggsb/nouveau/commit/11fcd1624b0a1c73fe3b2fa15c3cc45816da0470
Adds a check to nouveau that the gfx chipset is supported before booting fbdev 
off the hardware.
