Comment 28 for bug 430011

This actual bug here has been solved. What is left is a new regression discussed here:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/446146

Kernel bug here:
http://bugzilla.kernel.org/show_bug.cgi?id=14355

It seems like the patch did not make it into the release kernel, so the majority of mobile Ubuntu users are stuffed until the first service release.
