I have not looked into mini-os for a while. As far as I remember the low
level layers (exception, time and context switch) have to be rewritten for
ia64 (of course!). The higher levels (console) should be portable without
any change. The lowest level of event handler has to be rewritten too.
You have to look into linux-2.6-xen-sparse, both into arch/ia64 and
drivers/xen.
Feel free to ask more questions here.
Tristan.
