I'm not quite sure about the following:

- does Apus have it's own keycodes?

Yes, I think so. At least we need our own keymaps.

If not, do you currently use ADB or AT keycodes?
- what's the keycode situation in XF3/4 for Apus?

AFAIK it isn't very clean with either, the best bet is still to disable
Xkb.

APUS uses Amiga keyboards. There are lots of other machines who use their
own keymaps as well. If I only consider Linux/m68k, we have Atari, Sun-3,
Apollo, HP9000/[34]00, ...

I can't speak about XF4, but with XF3 all of these work out-of-the-box if
you disable Xkb (using kernel keycodes). If you enable Xkb, it also works,
but then you need the special X keymaps (for those that are available) (no
surprise).

And I'd say `everything else works fine if you use _MEDIUMRAW_ instead of
RAW'.

Nope, you need to compile xf3/4 with ASSUME_CUSTOM_KEYCODES undefined _and_
use RAW keyboard mode, otherwise it won't work correctly for some keys and
XKB. Tested that on PC and PMac, cause I wanted to be sure that my xf4 patch
is as short as possible.

If you want to keep the current state of affairs I can see in the
linuxppc_2_3 tree, there's not much point in using machid.c, AFAICS. On
the other hand, if you plan to integrate your input drivers into 2.4,
it makes perfect sense.

I think it would be nice, but to be honest I don't fully understand what
would be involved.

I hope this is _not_ about translating whatever-keyboard-type-keycodes to
PC-style keycodes? We (ehrm, I) already opened that can of worms somewhere
in 1995, and closed it ASAP.

Nope, Linux keycodes are linear keycodes from 0-511 (see
include/linux/input.h for a list), the range 1-127 is mostly PC compatible
though. Unfortunately NR_KEYS will probably not get bumped in 2.4, so
currently I have to map 5 keys back below 128.
