Egbert, The only thing I think that's missing from this is bumping the ddx version and the check in the Mesa driver to signify this change. I've already done the i810 (DDX) and i915 (Mesa) driver, so I'll commit this if you can modify the patch below to bump the version according to your change in the DDX as well.
