The rescue kernel will fail since initrd is broken. The backup initrd (at least with Linux Mint 4 XFCE, based on gutsy) is called: initrd.img-2.6.22-14-generic.bak You only need to rm the old one and copy the backup to it's place, then you should be OK. Of course you need to do this using the Live CD, mounting the drive then finding the boot directory.
