Well, Lenard Lindstrom has some time ago contributed a module like that
which is available in the (more or less unmaintained) ctypeslib project:
http://svn.python.org/projects/ctypes/trunk/ctypeslib/ctypeslib/contrib/pythonhdr.py

However, it was probably more meant to provide a complete Python C api,
instead of concentrating on stuff not available to Python otherwise.
