Well, it would need the host bridge which it doesn't have and it would need a concept of mapping that to interrupt numbers which we don't want in the kernel. We can keep the kernel side a LOT simpler (completely avoiding the whole route bloatware) by sticking to our "simple" direct map kernel stuff and doing the mapping from address/data to interrupts in qemu, so we'll stick to that. Cheers, Ben.
