Thanks, it works.  I didn't realize you could cast a Python object  
like that.  For completeness, this is what I used:

cdef extern from "object.h":
     ctypedef struct PyTypeObject:
         char *tp_name
     ctypedef struct PyObject:
         PyTypeObject *ob_type

cdef unsigned long type_addr(object object_):
     return <unsigned long>&(<PyObject *>object_).ob_type
