Cool!
Does it now happen that qemu no longer wakes up every 10ms? If not,
please try to make sure it happens, that would eventually fix that power

It is no longer required, but see below.

You can get to the monitor the same way in vnc as you do with the sdl gui.
You can also have the monitor connected to a socket or network port.
