That's the main difference between your approach (reimplement a
firmware) and the approach being developped here at XenSource (embed
qemu in a tiny stubdomain).  Your VMX work in Xen is most probably
something useful, but reimplementing the hardware emulation support of
qemu looks to me like duplicate work.  I haven't ported my stubdomain to
ia64 yet, but that shouldn't be very hard now that it works for x86.
