Hi Ajax,

sorry about the long delay. Sure, reading the code hints that it will
be centered.

Except that the modes are being ignored, OR taken to mean I actually
have a smaller screen.

So my question is actually: how do I write a modeline that gets Xorg
defining the available surface as being 1024x768 while still pushing
1200x900 pixels down the pipe.

Is it possible at all? My tests hint that no, Xorg is too smart for that.
