According to
https://github.com/dingusdev/dingusppc/blob/master/devices/macio.h this is
probably the ethernet port, may want to map some unimplemented device
there to log access, otherwise it probably OK ans could do without it for
now.

Still not sure about this one I'd expect it to write to frame buffer at
this point but probably it's accessing wrong area due to something
nonsense returned by some earlier read of some register and it did not
seem to talk to PCI devices to set up the BARs earlier so either we're
missing some register writes that are silently discarded in some
partially emulated device or it expects things to be already set up some
way at startup.
