Well, there's my autosuper recipe you've seen before:
http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/286195

which does basically what Philip descibes ...

>>> import autosuper
>>>
>>> class A (autosuper.autosuper):
...     def test (self, a):
...         print 'A.test: %s' % (a,)
...
>>> class B (A):
...     def test (self, a):
...         print 'B.test: %s' % (a,)
...         self.super(a + 1)
...
>>> class C (A):
...     def test (self, a):
...         print 'C.test: %s' % (a,)
...         self.super.test(a + 1)
...
>>> class D (B, C):
...     def test (self, a):
...         print 'D.test: %s' % (a,)
...         self.super(a + 1)
...
>>> D().test(1)
D.test: 1
B.test: 2
C.test: 3
A.test: 4

It uses sys._getframe() of course ...
