Excellent, thanks!

Here's an incomplete todo for spec compliance: note that it does not
have to block this patchset:
        - complete other devices besides net, balloon
                need to disable a bunch of features
                that 1.0 has deprecated

        - prevent DMA and interrupts until DRIVER_OK is set
          (but only when using modern interface)
                this interacts in a complex way with
                pci bus master hacks

        - go over devices, make sure they don't rely on io vec layout
