So when I did the MSI stuff I had assumed (apparently incorrectly), that PCI 
functions would only every have 1 non-MSI interrupt (since there is only a 
single INTLINE config register).  Is the extra interrupt coming from OF?  If 
so, does OF support MSI at all?  You could always change the OF PCI bus 
driver to not do MSI and use rid 1 IRQ for the OF indicated IRQ for a PCI 
device by having custom alloc_resource/setup_intr/teardown_intr methods.
