I see:

ohci.registers = (void *)fix_to_virt(FIX_OHCI1394_BASE);

then I think it calls:

set_fixmap_nocache(FIX_OHCI1394_BASE, ohci_base);

I'm guessing somewhere with the fix_to_virt might be something
(but could be wrong);

No, it ought to be that set_fixmap_nocache().

hmm..
as a quick test I did try:

set_fixmap(FIX_OHCI1394_BASE, ohci_base);
(maybe ohci_base)

which still hit, maybe something else
in the set of calls is hitting
i.g. address specific or something.
(I'll have to keep looking on this);
