Will Xen support the fw_cfg interface? If so, passing this info
should be possible through that interface. Another thing to consider
would be if coreboot+SeaBIOS in place of hvmloader would be a fit. (I
don't have a good feel for what hvmloader does to judge that.)
Using the coreboot tables in Xen seems a bit odd, but I can't say it
would cause a problem.
