I tried this on a Fedora Rawhide, I tried to rebuild the provided 3.16.0-0.rc4 kernel with the patch. After reboot, I still don't see scaling mode in xrandr properties, so no, it doesn't work for me. But maybe I did something wrong somewhere, that's very possible.

I suspect you aren't using the patch version of the driver. You should see the property. drm_object_attach_property() is what attaches the property to the connector.
