I had that as first version but other guests may expect the serial at the 
default address or set it up differently and we can emulate the device 
more fully this way that works with all guests which is also more like the 
device works. So putting it at a default address would be a step back. I 
can attempt that if this approach cannot be used but so far nobody said 
so.
