Accepted answer

Although not ideal, this would give you some event for regular and drilldown:

chart: {
    ...,
    events: {
        drilldown:  function (e) {
            console.log(e.point); // The point, with name, that was clicked
        }
    }
}

Along with your own code this would fire one event for regular points (your own code), and two events for drilldown points. You would then be able to check name == null in series.point.events.click, and ignore it, and handle it in chart.events.drilldown (API reference).

This is fixed now in the current development version of drilldown.src.js: http://jsfiddle.net/highcharts/Pq6gb/3/

point: {
    events: {
        click: function(e) {
            console.log(e.type, this.name);
        }
    }
}
