You probably want to have two scale-dependant WMS overlays -- one with a
minScale: 1000000, maxScale: 10000 , the next with a minScale: 10000 ,
maxScale: 1, or something. If you don't have another base layer,
creating an empty base layer:

  new OpenLayers.Layer("", {displayInLayerSwitcher: false, isBaseLayer:
  true});

Can be used.
