I didn't plan to add such detection into an initial driver code,
because it's already rather large and not very easy to review. Is that
fine to leave it as is so far and extend later?

PS BTW, I have updated v4 of this patch which fixes most of the comments
to the current one. I forgot to include checking XML def for apci/apic
(as you have pointed out), but I'm wondering if I should wait for
comments on v4 to submit it along with other fixes or send v5 with
acpi/apic flags right away?
