It's not the same hardware and all the machines that I tried that
have keyboards end up WORKING with the USB keyboard as well!  But
Dmitry Torokhov was right! I just burned a CD with all three modules,
and the keyboard works! I didn't bother to check the DEBUG messages.
It's interesting that the "wrong" module loaded fine with no warnings
that it might not be the correct one!

Thanks a lot.
