Interesting; sure enough, there's the 2048x1536 resolution that shows up in
the plymouth log, and 1680x1050 does not appear in the vbeinfo list.

So it looks like you're going to end up with a stretched GRUB menu no matter
what, because there are no widescreen 16:10 modes in the list.

That leaves two questions:

 - why does the plymouth drm driver not work on your card?
 - why does the nouveau framebuffer pick up the resolution passed by GRUB,
without cross-checking it against EDID?

These are probably both bugs that warrant further investigation.

Title:
  [nouveaufb] Plymouth refuses to show on boot, only at shutdown
  (mountall error messages)

Status in “plymouth” package in Ubuntu:
  Confirmed

Bug description:
  On my system, Plymouth shows properly on shutdown, but at boot I get a
  blank screen and an error from my monitor saying "No Signal", followed
  usually by some terminal text mentioning something like "mountall:
  Plymouth command failed".

  Then the Unity greeter comes up and everything after that runs just
  fine. It'd still be nice to see the boot splash, though.

  I've been getting this problem since I installed the 9/9/2011 daily
  build of Oneiric, but didn't get around to reporting it until today
  for some reason. Not sure if it's related to the fact that I cannot
  get grub to display either, despite this being a dual-boot between
  Oneiric and Natty, but I'll file that separately.
