By *this* do you mean the specific quirk that I sent or the whole offse= t 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.
