Ron unless you have something better I'd suggest using one of the
upcoming dual Itanium/P4 chipsets as a starting point.  Then you could
be certain the chipset worked before on x86 before trying to reverse 
engineer the cpu initialization for the Itanium...  

That isn't a very aggressive plan but unless we start moving in a
hurry it is probably a very workable one.
