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
