Besides that..there is:

9846ff1 xen: support pirq_eoi_map
(and its fix) 521394e xen: use the pirq number to check the pirq_eoi_map

In my case it is definitely IRQ related. From xl dmesg I get

If you revert those two, are those issues still present?
(XEN) physdev.c:164: dom0: wrong map_pirq type 3

This is one is due to another one - a fix that went in 3.3 (allowing
PCI domains to work).

(XEN) do_IRQ: 1.240 No irq handler for vector (irq -1)

So vector 240...or 0xf0. That I am not sure about.

40 and 240 should be IRQ 0 and 1

Incidentally, I have had IRQ problems with this computer before, eg. see http://lists.xen.org/archives/html/xen-devel/2010-08/msg01390.html though that turned out to be on the xen side.
