Sure, that's legal (though crazy). Besides the xorg.conf ServerLayout
syntax for positioning a Screen "RightOf", "Below", etc, you can also
set the screen's absolute position.

On another note: When Xinerama is active, it sticks the root window
dimensions in the ConnectionInfo global structure. Does that make this
any easier, or otherwise is there an opportunity for sharing code there?
