Is this an interesting use case? XenServer, for example, doesn't
present a PV frame buffer to any PV guest and I don't recall anyone ever
asking for it. There are better technologies for graphical remote
access (e.g., remote X over SSH, RDP, VNC...).

Really? What? There shouldn't be anything extra for a pure PV guest vs
a PVHVM guest (which RedHat do support).]
