Dan,
Can you pull xen-unstable-ia64-Intel.hg into Xen-unstale-ia64.hg?  We
have also push VT-I stuff based on Rev#5946 last night.  They are mainly
VT-I specific and does interfere with Xenlinux support.
We do modified files: xen/arch/ia64/patch/linux-2.6.11/irq_ia64.c  as a
separate patch on Rev#5952.
Thanks,
-Fred
