To reply to myself once more...

Yes, this is the problem.  I put a breakpoint at 
extended_type_info_typeid.hpp:96, and it is not being called for any 
types which I serialize *only* via base class pointer.  For types that 
are serialized through most-derived pointer (sharing the same base as 
the others), an extended_type_info_typeid_1<T> is getting created for 
each one.
