From: Tormod Volden <debian.tor...@gmail.com> Although these cards have 2 pipelines on the silicon only the first passed the QA and the other should be disabled.

So to play safe we should do it as well. I discovered this while studying a corruption issue report. Unfortunately this patch did not fix the issue, so I have no confirmation of this patch actually fixing something. I have a gallium and kernel patch ready if this one is approved.
