I tried again with the 6.7.194 driver.  Photos, README, and files are
here:

  http://people.ubuntu.com/~bryce/triple-head/

Essentially, after switching to tty1 and back, all 3 monitors displayed
without corruption, however monitor 3 was inaccessible by mouse or
keyboard.

Also, it brings up a question.  How *would* one configure multi-board
setups with xrandr?  I notice the screens on the second card have the
same identifiers as the screens on the first card.
