Hi,

I think that passing both layers to the select control should work:

selectControl = new OpenLayers.Control.SelectFeature([layer1, layer2]);
selectControl.events.register("featureselected", map, onFeatureSelect);
selectControl.events.register("featureunselected", map, onFeatureUnselect);
map.addControl(selectControl);
selectControl.activate();
