It's documented http://docs.djangoproject.com/en/1.1/topics/forms/modelforms/#overriding-the-clean-method? that if you override clean() on a ModelForm and fail to call ModelForm's clean() method, all you lose is validate_unique. With the recent model validation changes, this is no longer true; ModelForm.clean does quite a bit more (including constructing self.instance), and failing to call it will almost certainly break things.
Per discussion with jkocherhans in IRC, it should be possible to rearrange things to maintain the previously documented behavior.
