I would think you could fix things up with a rescue disk pretty easily.
The rescue kernel will have the needed device drivers and you can chroot
to /mnt/sysimage and then run mkinitrd to fix up the initrd img files.
If the architecure and disk layout is the same this should cover most of
your configuration. Things that are missing are mostly going to be per
user preferences on which dvd drive is the default and the like.
