Not very "stable" yet, but the current integration branch for Raphaël's work is at git://git.debian.org/users/hertzog/dpkg.git pu/multiarch/snapshot/20110210.

Currently the behavior is exactly what you describe, but I guess if that's a requirement, you'll want to communicate that with the dpkg authors. > Foreign suggests further more that the native architecture is not in the > list.
