So the Ubuntu backport from xen-unstable to Xen 4.1.1 is here:
https://launchpadlibrarian.net/81948978/xen-pirq-resubmit-irq.patch

It seems to be shipping in Ubuntu 11.10 xen 4.1.1-2ubuntu4.1 packages.

Does that patch look suitable to be applied to xen-4.1-testing.hg ? 
This bug should be fixed for Xen 4.1.3.
