A BH with these characteristics obeys the Kerr Metric (discovered by Roy Kerr back in the early 60's). These types of BH's are a little more complicated than your Schwarzchild hole.
In any case, if you have a complete law of quantum gravity, you can dispense with the singularity altogether because at a quantum level, the energy and mass of the hole become part of spacetime/superspace.

This is a valuable piece of information.
.. Probably the most valuable since the original post !
Thanks (again) Carl.
Cheers
