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.
