  While experimenting, I confused the VT manager somehow and I had
multiple copies of Xorg+intel running successfully. Even XGetImage was
returning "good" results! I believe that it worked because it was doing
everything thru DRI. Unfortunately, I can't figure out how to confuse
the VT manager on demand. :-(
