By *this* do you mean the specific quirk that I sent or the whole offset workaround suggested and upstreamed in the bug report? Actually I sync'ed the video driver from linux-2.6 on top of 2.6.31.13 and applied this patch. The user reported that it fixed the issue but it is possible that this quirk is NOOP and the bug is already fixed with what I've backported. I'll let him try without the patch, and report back.
