We already allow the user to specify display="on" and ramfb="on" for

Apologies. The context is that we currently support enabling display and
ramfb support for hostdev vGPUs, but only for those using the mdev
subsystem. However, going forward, some graphics cards will no longer
use mdev for their vGPUs. In order to maintain the same capability for
these devices, we can also enable it for other PCI passthrough devices.
Apparently this is something that's used heavily by layered products
like OSP.
Cheers,
Jonathon
