In the common case we only check for the displayable area.  We should 
split the region into two, one for the displayable area and one for the 
offscreen framebuffer (the boundary changes dynamically with the 
resolution).  If qemu can tell us nobody is looking at the screen, we 
can dirty tracking altogether.
