Re: [Xen-devel] PV drivers for HVM guest

After some more hacking, if I were to use the irqline information available in 
the pci config space for this device, both in establishing the handler  for 
this device (request_irq()) as well as in registering the callback irq 
(set_callback_irq()) things seem to work.
