Xinerama is mostly broken with xserver-xorg-core 1.4 and it might not be
fixed soon. I am merging with bug #443274.
RandR 1.2 is the new shiny way to manage dual-head. But the nv driver
only supports RandR 1.2 for G80 board. You seem to have a G84 so you
should be able to use it. You need to update your xorg.conf to do so.
