I'm not sure this is what you want, but you can change the VGA screen
(the one that lists all of the inits with the [OK] status) using a
kernel command line option vga=. The list of possible sizes is:
# colour depth | 640x480 800x600 1024x768 1280x1024
# 256 (8bit) | 769 771 773 775
# 32000 (15bit) | 784 787 790 793
# 65000 (16bit) | 785 788 791 794
# 16.7 Mill. (24bit) | 786 789 792 795
some of these may not work on your machine however, (I can't get a
1280x1024 screen even though that's the default of my monitor and X
supplies it)
note that this does not change the screen that GRUB is on (I don't
believe it is possible to change that, at least not very easily and GRUB
itself seems to require a certain size and depth as well. All of this
will likely change when GRUB2 is complete anyway!
