I'm guessing the problem is that it can't find root for some reason because of
a wrong root= option or something similar (like I said, a guess).  

If you remember what partition has /root (fdisk -l /dev/whatever from busybox
should help jog the memory), and if you didn't do anything odd with raid or
whatnot, you should be able to mount the root partition and 'exec switch_root
/rootmount /sbin/init' or something like that to boot the system.

If you don't want to even mess with switch_root, you could use the shell to
mount wherever /boot lives, and edit grub/menu.lst to change the default.
