Any distro (any OS) can work with with any boot manager, but
- you might have to put more effort into it
- some OS's are weirder than others

So you are doing this from Mandrake? That is, you booted
into Mandrake and edited its lilo.conf to add Debian?

this would be append="debian kernel options"

If the assumption above (you booted Mandrake) is correct,
/boot will point into Mandrake /boot directory.

You'd have to mount /dev/hda7 (if only temporary), e.g. as
/mnt/ and edit [Mandrake]/etc/lilo.conf:
image=/mnt/boot/vmlinuz-2.6.5
       label="debian"
       root=/dev/hda7
       initrd=/mnt/boot/initrd.img-2.6.5
       append="debian kernel options"
       read-only

Then run /sbin/lilo, this should work, IMHO. YMMV.

Whenever you want to change anything in /etc/lilo.conf,
even if it concerns Mandrake only, you'd have to mount
/dev/hda7 again (it the same way as before).
If you want to change something in Debian, you'd
have to boot Mandrake, edit it, run lilo and boot back into
Debian.
