Here is the GeoServer 2.0(dev) working example:
http://64.222.187.168:8080/gs20x/ows?SERVICE=WMS&VERSION=1.1.1&REQUEST=getmap&layers=shp:edges_merge&STYLES=roads_classified_shp_label&SRS=EPSG:4269&WIDTH=950&HEIGHT=600&FORMAT=image/png&BBOX=-96.79344550384396,32.76888304968294,-96.78588564285151,32.77365769873079

and MapServer 5.6.0beta2 should get the same response (with 
minfeaturesize auto and angle follow) but does not:
