Hi Jeremy,

today I tested the maverick alpha 1 and observed the same behavior as with lucid:
1. No extra kernel parameters:
  - vga16fb is loaded and not [u]vesafb
  - thus the framebuffer terminal does not work on my NC20 (maybe I should open a bug for this, too?)
  - no PAT entries are created by vga16fb
  - correct (write combining) PAT entries for "openchrome"
2. "video=vesafb:mtrr=3 vga=792" kernel parameter
  - vesafb is loaded
  - now the framebuffer terminal works correctly
  - "uncached-minus" PAT entries are created by vesafb
  - incorrect (uncached-minus) PAT entries for "openchrome"

Unfortunately the maverick alpha 1 ISO has no uvesafb in the initramfs, so I couldn't test this.

I will upload the apport files while above config 2. is loaded.

Kind regards,
  Thomas
