From reading the last several comments it looks like Intel was going to re-test on their M400 but so far there's no indications anyone has confirmed it fixed, so I think this got closed out too quickly. The downstream bug shows one user still reproducing the bug in precise as of June (dmesg and Xorg.0.log on that bug if interested).
