OK; sorry about the delay -- I needed to use the machinie for a while (at work), and then I had a weekly staff meeting.... Anyway... I've attached results of the above. For the first & last, I did each twice -- once using the "nv" driver, and once using the "nvidia" driver. (The middle one only got the "nv" driver.)
