Well, you can use generic relations without the backwards link, by simply looking up the content_type/object_id in the related class. But for your use case, a much better way is to use the built-in AUTH_PROFILE_MODULE setting, which allows you to nominate a class which extends User, and enables a user.get_profile() method.
