One step further: the problem is that pr->pblk is not set, thus 
acpi_processor_get_power_info_fadt fails.
Knowing this, I found an error in the ACPI_DEBUG output that 

[   17.062739] processor_xen-0222 [00] xen_acpi_processor_get: Processor 
[   17.062902] processor_xen-0225 [00] xen_acpi_processor_get: No PBLK 
(NULL address)

It does this for all processors. pr_id is always -1, pr->acpi_id 
counting up from 0 to 2.

Any help is welcome, but I will analyze further...

I have booted with a Live Linux and dumped acpi tables. Those are 100% 
identical with those
I received from Dom0. I will now start looking into 
acpi_processor_get_power_info_fadt And
check, why it is returning -ENODEV.
