Well I would, but with the assistance of Martin Bligh from IBM I've found my bug. Major thinko - there seems to be something funky in the 440BX chipset that allowed me to do something like:
outl(PCI_CONF1_ADDRESS(bus, 0, dev, fn), 0xCF8);
but still returned the correct PCI information! The problem was that I'd done my own inline for the addressing and, since I wasn't using reg, I'd left it out. Somehow I'd managed to shift the important stuff around...
Thanks to everyone who's offered suggestions and documents, it's much appreciated.
Cheers, Greg.
