No idea how > to reflect that PVH Dom0 isn't supported, yet. The fact that it isn't supported by Xen shouldn't be reflected on the Linux configuration, as it's independent. Ie: you could run this Linux kernel on a future version of Xen where PVH dom0 is supported. There's already a warning printed by Xen when booting PVH dom0 about not being a supported mode.
