Answering myself.
That does it all. Sorry for the noise.

<snip>
var wL = 'PSC';
var params = {map: mapfile, layers: wL, transparent: true};
var pos = "map.layer["+wL+"]";
params[pos] = somevalue;

	  var psclayer   = new OpenLayers.Layer.WMS(wL, 
  			                            http_mapserver,
                                                    params,
				                   {singleTile:true, isBaseLayer: false,
				                    wrapDateLine: true,
				                    queryable: true});
