I'm glad you brought this up, because when I implemented the tests, they
caught a bug in Gen6 transform feedback.  The patch is on the Piglit list
if you want to use it ("Test transform feedback with intervening
glReadPixels.").  Incidentally, I've sent a bunch of new transform feedback
tests to the piglit list in the last week.  I'm not going to try to
pressure anyone into code reviewing them until the new year, so if you want
to use them before they get reviewed, feel free to pull from branch "xfb"
of git://github.com/stereotype441/piglit.git

Happy holidays!
