The idea should be: when the user click on a certain point recognized by you, the popup should be displayed, isn't it?
You can do it in this way:
map.events.register("click", map , function(e){
// Look for point... (your code)
// Point detected!
// now we need to take the popup identified by 'popupid' identifier and show it
for(var i=0; i<map.popups.length; i++){
if(map.popups[i].id == myid){
map.popups[i].show();
break;
}
}
});
