int&& is a rvalue reference. Until C++11 we only had lvalue references. In Nontemplate_universal_ref(x), x is a lvalue, not an rvalue. Try the following:
template <typename ParamType>
void Template_universal_ref(ParamType&& param)
{
    cout << "Template_universal_ref, param : " << param << endl;
}

void NonTemplate_universal_ref(int&& param)
{
    cout << "NonTemplate_universal_ref(int&&), param : " << param << endl;
}

void NonTemplate_universal_ref(int& param)
{
    cout << "NonTemplate_universal_ref(int&), param : " << param << endl;
}

int main()
{
    int x=5;
    Template_universal_ref(x);
    NonTemplate_universal_ref(x); 
    NonTemplate_universal_ref(x+3);
    return 0;
}
Note that in the second call to NonTemplate_universal_ref, the argument x+3 is not an lvalue, that is, it cannot be assigned to.

Now, maybe someone can explain why the call via the template works?
