to be honest, i'm not exactly sure.
early on in the dmesg there is a line with whatever res i choose at the beginning:
Code:
Console: colour VGA 132x60
console [tty0] enabled
then after a bunch more lines there is this:
Code:
Boot video device is 0000:00:01.0
vga16fb: initializing
vga16fb: mapped to 0xc00a0000
Console: switching to colour frame buffer device 80x30
fb0: VGA16 VGA frame buffer device
fb1: Virtual frame buffer device, using 1024K of video memory
i'm fairly sure this is where it switches to the smaller resolution with a penguin logo. after this there's a bunch more lines and it finishes and launches gdm. i'm not sure if that answers your question though
