Yep.  Several of us do.

Yes.

Well, you are going to have to be more specific.  For lilo, the
partition(s) containing the /boot directory(ies) must be primary
partitions and reside entirely below the 1024-cylinder boundary.  This
is usually accomplished by making a 50-100MB partition for each
system which is mounted on /boot.

A good starting point is The Fine Manual:

http://www.redhat.com/docs/manuals/linux/RHL-8.0-Manual/ref-guide/s1-grub-liloconf.html

That shows a Linux system and a Windoze system.  Let's suppose you
partition your disk this way:

hda1     75MB  /boot # For 8.0
hda2     75MB  /boot # for 7.2
hda3     2xRAM  swap # for both
hda4     the rest for the extended partition
hda5     6GB   /     # for 8.0
hda6     4GB   /     # for 7.2
hda7     5GB   /home # for both
hda8     the rest # for anything, say /u, for both

Further suppose you keep the controlling /etc/lilo.conf on the 8.0
root (hda5).  Then you must mount hda2 (7.2 /boot) on (say) /boot72.
Then your lilo.conf might look something like this:

boot=/dev/hda
map=/boot/map
install=/boot/boot.b
prompt
timeout=50
message=/boot/message
lba32
default=linux

image=/boot/vmlinuz-2.4.0-0.43.6
	label=linux
	initrd=/boot/initrd-2.4.0-0.43.6.img
	read-only
	root=/dev/hda5
image=/boot72/vmlinuz-2.4.9-31
	label=rh72
	read-only
	root=/dev/hda6

Don't forget to run "lilo" after you build or modify your lilo.conf.
