Yes, at 0xfffff000. I tried hacking arch/mips/cobalt/pci.c however
so that it got mapped at 0x10108000 [Just commented out the check for
non-IO address space, what do I know :) ] but it still hung.

Ah, OK. I think I'll just try an PCI ISDN card that doesn't need
memory mapped IO, such as the Fritz AVM card.

Thanks
