Markus Brinkmanm (of HURD fame) has written this http://master.debian.org/~brinkmd/arch-handling.txt which is mandatory reading for us. they (the hurd people) are very interested in working closely together with us, simply since we together might have enough weight to make debian make more architecture aware. they are both highly cooperativ and competent, so we better are nice to them. (c: please give some feedback on that document.
