Here is what I am using for ublas::vector:

namespace boost {
namespace serialization {

template<class T>
struct implementation_level<ublas::vector<T> >
{
  typedef mpl::integral_c_tag tag;
  //  typedef mpl::int_<primitive_type> type;
  typedef mpl::int_<object_serializable> type;  
  BOOST_STATIC_CONSTANT(
                        int,
                        value = implementation_level::type::value
                        );
};

}
}

template<class Archive, class U>
inline void save (Archive &ar, const ublas::vector<U> &v, const unsigned int) {
  unsigned int count = v.size();
  ar << BOOST_SERIALIZATION_NVP (count);
  typename ublas::vector<U>::const_iterator it = v.begin();
  while (count-- > 0) {
    ar << boost::serialization::make_nvp ("item", *it++);
  }
}

template<class Archive, class U>
inline void load (Archive &ar, ublas::vector<U> &v, const unsigned int) {
  unsigned int count;
  ar >> BOOST_SERIALIZATION_NVP (count);
  v.resize (count);
  typename ublas::vector<U>::iterator it = v.begin();
  while (count-- > 0) {
    ar >> boost::serialization::make_nvp ("item", *it++);
  }
}

namespace boost { namespace serialization {
template<class Archive, class U>
inline void serialize (Archive &ar, ublas::vector<U>& v, const unsigned int file_version) {
  boost::serialization::split_free (ar, v, file_version);
}
}
}
