There are only -one- (1) each of variables named "marker" and "popup", even
though they're declared within the for-loop. Their values are whatever they
were assigned in the last loop.

Try this (untested):

  var doc = request.responseXML;
  var markers = doc.documentElement.getElementsByTagName("marker");
  function addL(mrkr,popup) {
      ATGEvent.addListener(mrkr,"click",function() {mrkr.openInfo(popup)});
  }
  for (var i = 0; i < markers.length; i++) {
      var p = new Point(parseFloat(markers[i].getAttribute("x")),parseFloat(markers[i].getAttribute("y")));
      var marker = new Marker(p);
      var popup = markers[i].firstChild.firstChild.nodeValue;
      addL(marker,popup);
  }
