If one of the current updateable DSi compatible flash cards were to use the ROM header, icon, and any other parts I might be missing, of a DSi enhanced game instead of whatever they are using now, wouldn't that possibly trick the DSi into booting it in DSi mode? Obviously this doen't mean DSi homebrew right away but it could mean we could finally enjoy DSi enhanced games in their full glory and start working in getting decent working dumps of DSi exclusive games. This is certainly a long shot but it's better than not trying at all right?
