They will support xrandr in the near future thanks to xorg-server 1.10! http://lists.x.org/archives/xorg-devel/2010-December/016606.html NVIDIA's position was that they could not support the Resize and Rotate extension since their driver couldn't access the mode-setting instructions provided by RandR as a whole, but rather each mode-setting step is submitted to the driver individually. Keith has changed this in RandR 1.4 by adding a new RandR request (RRSetCrtcConfigs) that allows the sending of all instructions over to the X driver in one step. Hopefully now we will see RandR 1.2/1.3/1.4 support finally coming to NVIDIA's proprietary Linux driver in the near future.
