this can currently be achieved (in a really sleazy way) by adding a
pci= line in the non-0 domain's config, and just handing it a device
that it doesn't have drivers for and so won't touch.
this is clearly not the, um, ideal approach to elevating privilege,
but it may get you going until the tools catch up. ;)
