if you are using the ntloader, i don't see what would be the problem with adding in the linux if you have XP and ME working. not that i've done it, but all the linux amounts to as far as windows is concerned, is just a file on your main partition (a copy of the linux mbr).
i'd set it up as on this website, except +ME, natch:
