As far as I know (and I study the airbus manuals regularly), there is no mentioning of any stick pusher. The idea behind an airbus is, that it cannot stall (?!). So why should they design something against a situation, that cannot happen? (not that I myself belief, that the aircraft cannot stall).
I also believe that an Airbus can stall, when it's computers and the pilots are not in sync. So I agree with you that a stick pusher would be useless in that case since it would likely be out of the loop as well.
