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!"
