[Bug 29352] High-resolution console doesn't work

[lyon]

Public bug reported:
https://launchpad.net/malone/bugs/29352

Affects: linux-source-2.6.15 (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed

Description:
I was using "vga=792" parameter on Breezy to run the console in high
resolution. This doesn't work anymore in Dapper (2.6.15-13) - nothing
shows up until gdm is started. "vga=normal" works, but I think people
need often higher resolution. Other things like dri are working fine in
X.

I have an Intel 915GM notebook, with Intel GMA900 graphics.
