I think of something like I wrote such a driver (yet without partitioning support) and I am trying to get it mainline, just didn't get any comments so far: http://patchwork.ozlabs.org/patch/23557/ http://patchwork.ozlabs.org/patch/23556/ I'd be happy if you could give it a try and donate some {Acked|Tested|Reviewed}-by tags. Maybe this will help for my next try to get it mainline.
