Ok, good to know. FYI, I also spotted that there are still some problems
left in the way DMA transfers are emulated (e.g. when the DMA transfer
size does not match the size that has been requested from the device),
and write access is also not working properly yet in all cases ...
so there is still a lot of work to do here :-/
