Post some code. This works for me:

py> import __builtin__
py> builtin_import = __builtin__.__import__
py> def __import__(*args):
...   module = builtin_import(*args)
...   module.__signature__ = "kilroywashere"
...   return module
...
py> __builtin__.__import__ = __import__
py>
py> import htmllib
py> dir(htmllib)
['AS_IS', 'HTMLParseError', 'HTMLParser', '__all__', '__builtins__',
  '__doc__', '__file__', '__name__', '__package__', '__signature__',
  'sgmllib', 'test']
py> htmllib.__signature__
'kilroywashere'
