Have you deactivated other drivers/processes that are reading the keyboard?

I would expect if you want to provide this kind of functionality it should be provided in either the

(a) keyboard driver,
(b) terminal protocol handlers
(c) the X windows keyboard handler

Do you understand how a keypress/scan codes come from a physical keyboard and finally end up converted into ascii characters in an input stream to a logical console?

I'm looking at some of the code (on my system: /usr/src/linux-2.6.21.5/drivers/char/keyboard.c), and I just seem lost in the code. Do you have any documents on this subject that I should read?

You are in the middle of the kernel.

I suggest you read up on how drivers work and how they interact with the rest of the kernel.

Are you sure you really want to be doing this?

The real question is "why not try?" The worst thing that can happen is I don't succeed.
