And easy to do. See below.

- get yourself the linuxconsole CVS from sourceforge (codename ruby)
- copy ruby/.../input/amikbd.c to apus24tree/.../char/
- copy ruby/.../input/amimouse.c to apus24tree/.../char/
- modify apus24tree/.../char/Config.in and apus24tree/.../char/Makefile in
a way that CONFIG_INPUT_AMIKBD and CONFIG_INPUT_AMIMOUSE replace the
current amikeyb.c and amigamouse.c
- compile & install the kernel, with the following minimum options:
         CONFIG_INPUT=y
         CONFIG_INPUT_AMIKBD=y
         CONFIG_INPUT_AMIMOUSE=y
         CONFIG_INPUT_KEYBDEV=y
         CONFIG_INPUT_MOUSEDEV=y

- make sure _absolutely no_ keymap is loaded on bootup, on RH style setups,
this means "rm -f /etc/sysconfig/keyboard
/etc/sysconfig/console/default.kmap" (it may be a bit different, I'm
quoting from memory). The default kernel keymap in pc_keyb.c has to be in
effect on reboot.
- reboot with new kernel

Now, with the new kernel, most of the keys and the mouse (/dev/input/mice,
protocol ImPS/2 for X, imps2 for gpm) should still work. There are for sure
pitfalls in the above description, but these should be solvable by someone
knowing the [Cc]onfig.in and Makefile setup for Apus. You should at least
get to a point where you can tell if the ami*.c input drivers in the
linuxconsole CVS are useable already.

For Apus keycodes backwards compatibility take a look at what I did in
apus24tree/.../input/keybdev.c and apus24tree/../macintosh/machid.c. To
generate a conversion table, goto ruby/utils and do the following:

         gcc -Dfrom=code -Dto=atari gencodes.c -o gencodes
         ./gencodes

Well, the code at least looks like someone already worked on it, so it may
be functional.
