That would make sense if xen could use the graphics framebuffer, but
since xen currently only supports text mode the option really only
applies to dom0. I guess we might add support in future, in which case
parsing it from xen's command line is OK. This may have implications for
other dom0 OSes who are expecting to find the console in text mode,
