Fiddle with your /etc/lilo.conf

Use different "root=/dev/foo" for each setup.

On the actual root disk for each distro, you can mount the other distro
on different mount points in /etc/fstab

eg
/dev/hda1	/	ext2 	<options>
/dev/hdb1	/mnt/root ext2	<options>

Note that the file system itself can be mounted on any mount point. This
seems to be the piece of the jigsaw you were missing.
