Comment (by openlayers):

 Possible workaround/solution:

 Just add the following layer to your map...

 {{{
 var lyrBaseClear = new OpenLayers.Layer.Image(
         "None",
         '/path/to/clear.gif',
         new OpenLayers.Bounds(-180,-90,180,90),
         new OpenLayers.Size(8, 8),
         {isBaseLayer: true}
 );
 }}}

 ...where clear.gif is an 8 x 8 pixel transparent gif. You get a
 transparent base layer labelled "None" in your layer switcher. That works
 for me.
