I'd recommend following the same steps I outlined in bug 907055 which is to send the patch to the dri-devel mailing list (on lists.freedesktop.org).

An example of the e-mail I sent for bug 544671 can be found here: http://paste.ubuntu.com/784682/

Please keep this bug report updated with the result from the discussion so the kernel team can the cherry-pick the commit once accepted upstream and include it in the Ubuntu kernel.

Once submitted upstream, it would be great if you could provide some information on the status of the patch. What sort of feedback has it received, is it getting applied to a subsystem maintainer's tree, etc?
