It seems that it's definitely a driver problem, and a patch has been made to fix the issue. We're trying to push for inclusion as soon as possible. The corresponding bug-report is https://bugs.edge.launchpad.net/ubuntu/+source/linux/+bug/349314, you can track that bug for the fix (feel free to comment on it too).
Thanks for the extra info!
