Is SH3 the Hitachi SuperH chip? If so, you also need to do a sh port of UML,
and the best way to do that would be to port it to Linux/sh before porting to

The OS has to provide some interface to the device. If so, then UML goes
through the host in order to get to the device, so the next case is covered as
