I had a similar problem with drivers 8.24 through 8.27. Roughly one in three logouts, the screen would turn completely white. At that point, Ctrl-Alt-Backspace crashed the computer. After commenting out in xorg.conf:
 #Option "VideoOverlay" "on"
 #Option "OpenGLOverlay" "off"
it seems to work fine. :-)
