heh, yeah, you're gonna have a bad time with this:

[    1.834852] nouveau  [  DEVICE][0000:03:00.0] BOOT0  : 0x118010a2
[    1.834885] nouveau  [  DEVICE][0000:03:00.0] Chipset: GM108 (NV118)

How did you get that? I guess you copied the entire 0x117 section instead of
just adding the "case 0x118" next to case 0x117? [not that there's anything
wrong with that]

That's the vga 0x3d4 port afaik... no display controller? no outputs in the
dcb, so I guess that makes sense. Does it come up as a 3D Accelerator, or VGA
compatible controller?

Seems like an awfully low amount of vram :) Can you boot with
nouveau.debug=debug? That should provide some additional prints to work out how
it gets to such a fun quantity.

I'm very willing to believe that these issues are all caused by the negative
vram size.
