There is one in hw/dec_pci.c. This isn't compiled by default, but that
is just a configuration issue. I had some IRQ routing issues with that
one though.
There is also http://patchwork.ozlabs.org/patch/103058/ which works fine
after fixing the double irq_num. Michael wants implement hotplug
support before merging it though.
cheers,
Gerd
