I posted a third approach last night. For those of you following this thread there are now three streams: This stream, https://lkml.org/lkml/2013/3/16/168 (which is also on the linux-pci list), and https://lkml.org/lkml/2013/3/21/12 (which is also on the linux-pci list).
Perhaps the third time will be a charm
