I've not actually tried it, but I think the Debian HURD port got new wind a while back -- there are some references on the Debian/kfreebsd mailinglist that seem to indicate that some people are actually working on stuff on the HURD side (the former is a project to bring Debian "userland"/distro to the HURD kernel, the latter is the same for running Debian with a freebsd kernel (as opposed to a linux or solaris (see [ed:Nexenta, not Illumous as that is more of an Ubuntu/Solaris-thing] etc) one).
