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.)

So the files are:

kib_0_nv
kib_0_nvidia
kib_1_nv
kib_2_nv
kib_2_nvidia

Peace,
david
