That just disables the use of vram for exa pixmaps. You can accomplish the same thing by adding: Option "EXAPixmaps" "false" to the device section of your xorg.conf
Yes, the option helps a little: I can see the KDM screen without any artifacts. However, it is dead, i.e. frozen. Feels like a GPU lockup, but no error messages in Xorg log or dmesg. How can I get more info?
