Not sure what nwn is doing, it works fine with other chips, and chances are it wouldn't if it would really use VERT_ATTRIB_WEIGHT. Anything special about the areas where that's happening? There are workarounds in mesa core (and r200 driver) to make World of Warcraft work better, which also (errorneously) uses that, but that workaround is limited to fixing up vertex programs (which nwn usually doesn't use, except if some nv extensions are present IIRC), if an app tries to submit for instance a vertex weight array, it will not work. I don't quite understand where that attrib shows up in your case, but something seems fishy here...
