I think it never worked correct. But the patch can be backported without conflicts/reworks only for .37 stable kernel. Do you rather like to take it for v3.1?

Yeah, v3.1 would be fine - if it was broken for like 5-10 years then it's not eligible for -rc5. The linecount is very high as well, it's definitely not a oneliner fix ...
