I'm pretty sure I mentioned a way to do that back when this thread was 
opened.  let's see, yes, here it is:

...

there's a helper script in the 2.5 source code kit that locates all 
existing standard modules:

http://svn.python.org/projects/python/tags/r252/Doc/tools/listmodules.py

to get all modules, remove the for-loop that follows after the comment 
"get rid of site packages".
