I think this would actually be best fixed in your custom-partitioner udeb, although it was triggered by a change in mdadm in natty. Compare the corresponding fixes that we made to our standard partitioner:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=591917 http://bazaar.launchpad.net/~ubuntu-installer/partman-md/master/revision/1016
Could you try the attached patch, which should work in older releases as well as in natty?
