That must be due to the ModeLine entry in your xorg.conf file.  Try 
changing that label to "736x485",
stuff 736x485 with the i915resolution program, and retry the Xorg server.

I don't know if this ( xorg.conf-ModeLine + i915resolution) will work. 
Its not exactly the same as (display-provided-info + i915resolution),  
but, as they say, "cheers!"
