How to modify default keyboard map in PowerBook G4

[Amit Uttamchandani <amit.uttam@gmail.com>]

Hey Guys,

Just installed Debian etch and it's working great! Only issue is with Midnight
Commander. Debian has automatically detected the F1-F6 keys in the PowerBook as
brightness +/-, volume +/-, numlock, and mute, respectively. Now, I can't seem
to use MidnightCommander F1-F6 since they are mapped to the above mentioned keys.

Anybody has similar issues? Any suggestions? If I do remap the keyboard, how do
I adjust screen brightness as I am currently not using any desktop environment?

Thanks for all the help,
Amit
