OpenLayers doesn't talk to the WMS server at all, so it doesn't have
this information. I'm not aware of any current efforts to attempt to
download and parse GetCaps specifically for extents. (Lorenzo is looking
into it for adding layers, i believe.)

getDataExtent doesn't have any meaning for WMS layers at the moment, but
I had no plans to make it anything other than the current extent of the
tile grid.
