Linux - how to turn on framebuffer during boot process

Just write 'vga=some_number' into the menu.lst file (if you use grub - does anybody use lilo yet ? ;-) ). Example values for some_number:

1280x1024x64k  (vga=794)
1280x1024x256  (vga=775)
1024x768x64k   (vga=791)
1024x768x32k   (vga=790)
1024x768x256   (vga=773)
800x600x64k    (vga=788)
800x600x32k    (vga=787)
800x600x256    (vga=771)
