What does the mioverlay.c do in the mi module of Xfree86? I notice that 
    

   It supplements the original mi code.  Mi didn't know about anything
other than single layer framebuffers.  mioverlay adds a second window
tree and fixes up all window operations to be aware that, among other
things, overlay windows don't clip image layer windows.

So how does the chips driver implement overlay without  mioverlay?
