Unfortunately this is the expected behaviour currently. Due to shortcomings in our memory manager for this release we won't be able to resize the framebuffer from it's initial configuration. However, if you configure a non-cloned layout in xorg.conf as described at http://wiki.debian.org/XStrikeForce/HowToRandR12 you should be able to make this work.
