Is there a patch for the new MemoryRegion API?
At least for now, I need to be able to issue a single 64, 128 or 256bit transaction to a particular IO device. Is there a way I can do this now as a temp solution? I don't mind coalescing the bytes as they are issued by Qemu but I have no way to know that they're from the same instruction. Any pointers?

Not yet. The new MemoryRegion API will allow this, but we need to convert all the devices first, then rip out the old API. It's a work in progress... r~
