BOOST_SERIALIZATION_BASE_OBJECT_NVP isnt working in a non intrusive
case, since the macro uses this.
Hmmm  - this never came up before.  But look likes your correct.  The 
definition
of BOOST_SERIALIZATION_BASE_OBJECT_NVP is

#define BOOST_SERIALIZATION_BASE_OBJECT_NVP(name) \
    boost::serialization::make_nvp( \
    BOOST_PP_STRINGIZE(name), \
    boost::serialization::base_object<name >(*this) \
)

So you might try:

template<class Archive>
void save(Archive &ar, const my_class & t, const unsigned version){
    ar << boost::serialization::make_nvp(
        "base_class_name",
        boost::serialization::base_object<my_class &>(t)
    );
    .... // member variables of my_class
};
