If we are working with a WMS server that already provides a base layer and/or refuses to supply a base layer with Spherical Mercator projection, there is no way to transform the data to overlay the map. Right now OpenLayers decides to request Spherical Mercator projection anyway which returns XML error messages instead of PNG tiles which can then get plotted as big pink squares.
