Well, I can't explain the following based on the information in the bug tool, but I upgraded to 15.1(2)T (Adv Enterprise), and ipv6 is working on the bvi interface right now.

bridge XXX router ipv6 still does not appear as a possible command, but I put the ipv6 address on the BVI interface, and everything is singing and dancing as planned.

*****Thank you***** to anyone on list who was involved with making this work.
