Grub just boots off of the first kernel image in /boot/grub/menu.lst, if you comment out the latest kernel image and recovery mode (by prefacing the lines with #) grub will automatically boot into the first image listed in that file. I'd recommend backing up that file first, however, in case something goes wrong.
