Why do you think this? The keyboard isn't built in to the hardware,
so the set of keycodes you get depends on the keyboard, not the
Integrator/CP. (Conversely, you should get the same set of keycodes
for an Integrator/CP as you would for a PC model, so if there was
a difference in 0.10.5 this is a progression, not a regression.)
