The screenshots in the packages.ubuntu.com listing show the Debian graphic very prominently so we'll need to see if that is hard-coded or not. From the discussion on LP Bug #585853 it looks like Steve Langasek said XDM does not play nice with Upstart ten months prior to Micah's merge. Debian Bug #615020 talks about a lack of ConsoleKit support which is going to be crippling nowadays. More details can be found through the portal here: http://packages.qa.debian.org/x/xdm.html I might suggest considering a different option than XDM if possible. I might think of some Wednesday once I get a good night's sleep after a day On The Run in Cleveland handling business downton.
