The warning messages can be fixed by commenting out the warning proper, or
adding fake Linux keycodes for the few buttons that don't have a keycode
(I used 254 for a keycode), or adding a test to ensure the button
scancodes are not translated and sent on to the input layer ever. I can
send a patch implementing the second method. The third method might better
be implemented in adbhid.c:adbhid_buttons_input() rather than in the input
code (the code to report these button events to the input layer was only
added in adbhid.c and wasn't present in mac_keyb.c BTW. What was the
rationale behind this? Are you planning to move the backlight control to
user space?).
The non-functional backlight control is something I'd like to have
confirmed by other TiBook users - just ignore the console messages and
press the backlight control multiple times until the backlight turns off,
please. If it doesn't turn off after 15 key presses, something's broken
indeed.
