This is a bug in the RandR DDX code which should be fixed in Xserver 1.5.2.

Fix.

The attached patch fixes the problem. 
NOTE: This is *NOT* a driver issue although it seems easy to blame the driver used.
The problem only occurs with the specific order options used when the output specified is not connected. That's probably why it hasn't been found, yet.
