I just did tested this -- it seems to work after the control is added to
the map, and layers are added to the map. (It doesn't actually populate
the overview map until after it has a base layer to clone.)

var ovm = new OpenLayers.Control.OverviewMap();
map.addControl(ovm);
map.addLayer(wms);
ovm.maximizeControl();

Will that work for you?
