Hrm actually, it might well work with Linux regardless because Linux only ever does 8 bit accesses to the virtio config space. It's SLOF that breaks because SLOF uses 2 and 4 byte accesses (which are allowed per spec as far as I can tell) but the spurrious swapping happening in that case means we lost the byte address invariance.
