Answering my own question, I've got it working now, and I think the
magic sauce was to tell my OpenLayers the expected projection:

	var options = {
	projection: new OpenLayers.Projection("EPSG:900913"),
	displayProjection: new OpenLayers.Projection("EPSG:4326"),
	units: "m",
	numZoomLevels: 20,
	maxResolution: 156543.0339,
	maxExtent: new OpenLayers.Bounds(-20037508, -20037508,
        20037508, 20037508.34)
	};

        map = new OpenLayers.Map('map', options);

I haven't run this to ground, but my speculation is that WMS asks for
the projection, and barring that GeoServer offers it up in the default
for the layer.
