Boost.Move calls user defined constructors to operate, so you can 
implement your move constructors using your efficient swap:

Type(BOOST_RV_REV(Type) t)
   : ...() //Empty construction
{
   this->swap(t);
}

Ditto for move assignment:

Type & operator=(BOOST_RV_REV(Type) t)
{
   Type tmp(boost::move(t));
   this->swap(tmp);
}

Best,
