Yes, exactly so. Actually the input AT keyboard driver uses AT (as
opposed to PC/XT) scancodes natively, so no conversion needs to happen.

Now, if you could do the switch before 2.5 (in the ruby
tree), that'd help integrating the input stuff into 2.5 faster once
2.5 is out.

Its hard adding infrastructure and breaking working drivers even in a
development kernel, namely if the drivers are as important for use as
keyboard or console.
