Yes, that patch could be applied to 3.3. I chose not to mark it as Cc Stable as 
that card is not widely available, thus I did not expect the problem to harm 
many users. On reflection, I think I made the wrong choice.

Greg, could you please apply mainline commit 0298dc9 to 3.3-stable?

Thanks,

Larry
