Stefano,

Take a look at 
git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen.git 
pv/pcifront-2.6.32

It has a Linus 2.6.32 as a base and all of the patches necessary for PCI front 
to work. That includes a lot of patches in the events and the pirq/event 
channel to make it work. Also tie ins to the MSI/MSI-X and IRQ interrupts to 
have a PCI device work in PV guest.
