Ok. I forgot about this patch ... I still think there is a problem with the installation of the shared PCI interrupt handler, if I read the log messages corerctly. Are there actually motherboards, that have a PCI BIOS capable of assigning memory and I/O mappings to devices behind PPBs, but fail to setup the interrupt routing correctly ? I've seen a few MBs, that probe at most two levels of bridges deep (i.e. do support a AH3940 behind another PPB, but not in a PCI bus extension box, which got two PPBs (back to back) between its slots and the primary PCI bus).
