Michael,

I think the easiest way would be to add a free function to db_boards.h
that allowed you to register additional (dbid, factory) pairs to an
internal data base searched by instantiate_dbs.  You'd have to
register your new daugherboard(s) before instantiating usrp_standard_*

Maybe something like:

struct db_factory {
  virtual db_base *operator()(usrp_basic_sptr usrp, which_side) = 0;
}

void db_register_dbid(int dbid, db_factory f);
