Comment 95 for bug 118745

Doesn't work with newly released ati driver 6.7.195. Alex Deucher tells that this is probably xserver issue and not ati driver one: http://lists.freedesktop.org/archives/xorg/2007-September/028627.html. Unfortunately xserver devs didn't respond to that so this is still unknown.

If you are xserver dev and could help to track down this I'm ready to test your ideas, debug things and so on. Very nasty issue preventing any few randr 1.2 drivers from being usable :-/
