I found this patch after some googling and for the record, it makes my
W520 boot with VT-d enabled and the discrete NVidia card.

Yes. I am still in pushing the patch to upstream. The patch is good and reviewed
by Yinghai but it depends on Yinghai's patch which is not upstream now.

Peter, will you take it?

Thanks
