This required a few more hacks, but it works now.  The problem is not
with Coreboot, but with Xen assuming that there is a BIOS it can call
to setup the video display and also assuming that there is an EBDA
that contains pointers to various structures.

My 4.6.3 Xen tree is hacked up right now with stuff copied from old
versions of the tree, so I'll clean it up and see if they are interested
in accepting patches.
