I've lost track of the state of the QEMU patches but, if they go in, then it should be completely reliable. If not then it will be non-functional... but the same would be true of the Linux frontend running in an HVM guest. (The patches fix a bug where xenvkbd and xenfb are interdependent... but the xenfb backend is only created in the xenpv machine type).
