Breezy installer resolution

[Carey O'Shea]

I've just installed Breezy Colony 4, I'll be testing it out tomorrow.

Just one thing though, I've always wondered why I experience display 
problems with the Debian installer (on both debian/hoary/breezy) on my 
laptop. The bottom of the screen is squashed and rolled up to the top. I 
need to always append vga=771 (which is 800x600 at 256 colours) or 
vga=769 (640x480, 256 colours) to get the installer to display properly.

If the installer doesn't use 769 or 771 by default, then what does it 
use? I have a desktop PC that is 12 years old that can display 769 or 
771 resolutions, so shouldn't all more recent PCs also have no problems?
