All Content Model objects *should* contain the triple that Adam has identified, the triple isn't generated automatically (however if an object declares no content model, then a triple will be generated identifying the "default" content model - info:fedora/fedora-system:FedoraObject-3.0).
I'm not sure if the CMA works correctly if a Content Model object fails to declare that triple, perhaps that's what is going on in this case? It would be useful to confirm if (a) the RELS-EXT of the CModel objects do indeed fail to declare that triple and (b) if any objects belonging to that CModel "work" correctly wrt object methods etc. If you want to query for content models *in use* by objects in the repository, you could use the query select $o from <#ri> where $s <info:fedora/fedora-system:def/model#hasModel> $o and use the "Force Distinct" option in the risearch web interface (or the distinct=on query parameter if calling the risearch service directly).
