Right, but recall, we're passing this up through to the PS/2 layer so it 
will just appear like the local keyboard is connected to the server.

One problem with passing Linux input codes is that we have no way to 
make the information we get from GDK to Linux keycodes.  We're basically 
passing all the information we have (the symbolic value, and what GDK 
provides as the hardware keycode with some canonicalization).

What can we do in the client to convert to Linux input codes that we 
couldn't do in the server?
