I got those fixed too - was using 'xen_irq_from_gsi' while
it should have used 'xen_irq_from_pirq'. This was the new mechanism
to obtain the vector values after .. 2.6.38-rc1 ish.. (as the
GSI values now have the correct value of zero, and the vector value
for MSI/MSI-X is written in the PIRQ entry).
But those patches are in a different branch (devel/xen-pciback-0.3).
