This doesn't seem very compelling to me. Either userspace
should just be fixed or the kernel should implement a namespace
for serial ports which doesn't randomly change just because the
particular h/w driver doing the implementation is different.
We shouldn't be papering over other peoples' problems in the VM
spec IMHO.
