I am not sure what exactly the bonus is, but it's a special ability (and thus cannot be combined with other special abilities) and in my short time playing vanilla BI I haven't seen a berserk unit routing. Since Gaesatae and other barbarian elites could and did rout, I don't think it would be realistic.
