Works fine in Python 2.5.2 also::
Python 2.5.2 (r252:60911, Aug 8 2008, 11:09:00)
[GCC 4.3.1] on linux2

>>> module = type(__builtins__)
>>> module
<type 'module'>
>>> '__call__' in dir(module)
False
>>> import sys
>>> class CallableModule(module):
... def __call__(self, *args, **kwargs):
... sys.stdout.write("%(self)r, %(args)r, %(kwargs)r\n" % vars())
...
>>> '__call__' in dir(CallableModule)
True
>>> foo = CallableModule('foo')
>>> foo(1, 2, 3, a=4, b=5)
<module 'foo' (built-in)>, (1, 2, 3), {'a': 4, 'b': 5}
>>> foo
<module 'foo' (built-in)>
