Hmm; I must be missing something... cuz to me it looks like pci_32.c will allways call pcibios_init, which will will scan the bus, which will swizzle irqs if the platform has non-null swizzle and map_irq function pointers defined.. Perhaps a setting I've missed somewhere re. 'pci_auto', which I thought was a 'ppc' thing, not a 'powerpc' thing..?? -dbu.
