This is a patch to switch ppc from using Yaboot to using Grub2. Because the default
terminal size is 80x24 and Open Firmware's default size is a little larger than that
so repaints will mess up the display. Therefore, tell grub to configure
'terminfo -g 80x24 ofconsole'. We do this with a new GRUB_TERMINFO variable and
enablement script in grub.
