Dragons lurking here.  It's not the first attempt to ditch this, and so
far all have been rolled back due to regressions.  Specifically Xorg is
notoriously picky if it doesn't find its expectations fulfilled.

Also note that pci is not the only virtio transport we have.

What kind of testing has this patch seen?

take care,
