100.14.23 - this driver works fine (but a bit slower than 169.xx).
169.07 - Xorg Server is crashes periodically.
169.12 - Xorg Server is crashes periodically , but not so often as 169.07 version.
169.12 - graphics corruption on the screen
all drivers - After a few days of using the Xorg it will be impossible to output video through "Xvideo" (mplayer -vo xv). A mplayer window becomes corrupted.
Developers, say me, please, that you took it into account. (-;
