Hi Peter,

I would tend to think that there is only one correct set of key codes that the
keyboard on Integrator/CP may generate. And the question is whether  
the current
behavior is the correct one.

We can observe this with HelenOS/arm32/icp. We captured the key codes of the
layout from the old Qemu and programmed our driver to work with, but with the
new Qemu, the key codes / the layout changed and the driver sends wrong codes.
