When booting from CD in rescue mode, have you tried skipping the scan
for RedHat systems? This will get you to a shell prompt without
mounting anything.

OTOH, I've never had any probelm umounting the /mnt/sysimage
directories. If any of them are mounted on a root mountpoint, you have
to unmount all of them before you can unmount the root partition.
