I haven't used it, but this project looks like what you're looking for:
https://code.google.com/p/django-polymorphic-models/

You can request LessonModule.objects.all() and then .downcast() each object automatically into a ProfileImage or a Note.

Or add the PolymorphicMetaclass to your LessonModule to always retrieve ProfileImage and Note objects from a queryset.

Note the cost of extra queries... polymorphism in Django models is done via table joins, not pure python code.
