Aren't you talking about the struct module? In ctypes, it seems it
would be sufficient to add a "c_int128" type (and/or "c_uint128").

Probably because noone needed it until now?
We have a comprehensive guide if you want to contribute a patch:
http://docs.python.org/devguide/
The first step would be to open an enhancement request on the
issue tracker, the discussion will then move on there:
http://bugs.python.org/
(if you want to enhance both the ctypes and struct modules, please open
a separate issue for each)
Regards
Antoine.
