There must be an OFW-tree entry with a name or device_type of "interrupt-controller". NetBSD/ofppc works with the Pegasos 2, which is an OpenFirmware machine with i8259 PIC. So theoretically it should work. OFW PIC detection is in src/sys/arch/powerpc/pci/pci_machdep_ofw.c genofw_find_ofpics(). -- Frank Wille
