The imp module is not yet updated to have full access to the new import hooks :-(. See near the end of http://www.python.org/peps/pep-0302.html for a discussion of the issues.
There's another minor issue with the new import hooks which would be nice to be fixed: to my knowledge, the Py_VerboseFlag is not exposed to the Python layer. Sometimes it would come handy when debugging a custom importer.
