I couldn't get getDataExtent()) to work for a OpenLayers.Layer.GML
I changed to a OpenLayers.Layer.Vector and then it worked:
var g = new OpenLayers.Format.GML();
var fbndurl =
"http://10.65.192.1/cgi-bin/agbwfs.exe?farmid="+farmid+"&request=getfeature&typename=farm&service=wfs&version=1.0.0&SRS=EPSG:2193&BBOX="+x1+","+y1+","+x2+","+y2+"&maxfeatures=120
(
'http://10.65.192.1/cgi-bin/agbwfs.exe?farmid="+farmid+"&request=getfeature&typename=farm&service=wfs&version=1.0.0&SRS=EPSG:2193&BBOX="+x1+","+y1+","+x2+","+y2+"&maxfeatures=120'
)";
OpenLayers.loadURL(fbndurl, '', this, fbndreturn);
function fbndreturn(fbndresponse) {
fbnd = new OpenLayers.Layer.Vector("Farm boundary",
{isBaseLayer: false,
style: farm_style,
extractAttributes: true });
fbnd.addFeatures(g.read(fbndresponse.responseText));
map.addLayer(fbnd);
map.zoomToExtent(fbnd.getDataExtent());
}

The singleTile option is completely useless... as is the
extractAttributes option, I'm pretty sure...
Anyway, "yes, as of 2.7."
