Bug#441902: xserver-xorg-video-ati: 6.7.192-1~7.2 crashes xserver with xv video playback on compiz

[Timo Aaltonen <tjaalton@cc.hut.fi>]

this was reported on Ubuntu too:

https://bugs.launchpad.net/debian/+source/xserver-xorg-video-ati/+bug/141533

and reverting commit 5d044b9f74c7aa7e12f2822896fed881e2ca9d19 provided a 
workaround for now.
