It is a bit strange, since most of the xen acpi processor panic is caused by 
incorrect processor id (pr->id), the ACPI method evaluation (like "_CST" here) 
should not relate to this.

BTW, does xen/master branch or bare mental works in this machine? And in the 
i686 box that works, can 'xenpm get-cpuidle-state' show correct Cx information?
