In general, OpenLayers does not have information on the client side to provide the WMS extent. Using a WMS GetCapabilities request is the only way (via WMS) to get that information. There is a plan for a WMS GetCapabilities format, which could read WMS GetCaps data, at some point in the future, I believe. I don't know if reading the Layer extent is planned as part of this development.
