Hagen,
does this simple patch (against 2.6) solve it for you?

         # Subclasses may override this
+        if module == "builtins":
+            module = "__builtin__"
         __import__(module)
         mod = sys.modules[module]
         klass = getattr(mod, name)

I think a dict mapping the moved modules would work better, perhaps
having it in PyPI would be enough?
