I just upgraded my Debian Lenny to Squeeze. The problem is, I'm using an old IBM PS/2 monitor that won't support anything other than the plain old standard 80x25 screen. (Not even 80x50 is compatible.) Grub got upgraded from 0.9 to 2, and I successfully got it to stop using the framebuffer. The problem I can't figure out how to fix is, once it starts to boot up, the console goes into framebuffer mode.
