Yep, they do. So, layer.resolutions is ignored for all but the base layer. I look forward to talking about fixed resolutions and "base layers" for 3.0. We've got a number of applications that don't differentiate between overlays and base layers. That is, any layer can be displayed as the lowest layer in the draw stack and any layer can be used to determine projection related parameters. For this to work (effectively switching isBaseLayer from false to true and back), the initResolutions call is needed somewhere. (In case you were going to suggest doing away with it.)
