Comment (by Markus Holtermann):

 When I try to run `makemigrations` after *step 0* with the code you
 provided I get the following system check failure:
 $ ./manage.py makemigrations
 SystemCheckError: System check identified some issues:

 ticket26488.SubModel.basemodel_ptr: (fields.E007) Primary keys must not
 have null=True.
         HINT: Set null=False on the field, or remove primary_key=True

 Further, neither steps 0-2 nor steps 1-2 work for me. It comes down to
 `django.core.exceptions.FieldError: Auto-generated field 'basemodel_ptr'
 in class 'SubModel' for parent_link to base class 'BaseModel' clashes with
 declared field of the same name.` both times.
