What about a simple example where you set write a bit plane mask into a graphics register, then write some data to the framebuffer? You can't have two programs doing that at the same time!
This could easily occur if an X client were directly manipulating the framebuffer at the same time the X server was doing the same, or if you switch away from X (with the server still running...) and try to play a graphics game on the framebuffer console while your kernel compiles!
