Graeme,
Did you get any useful answers to your questions?
I have just purchased a similar keyboard (Logitech Internet Navigator
Keyboard, PS/2 and USB, corded, 13 buttons + 8 multimedia controls).
It has a primary USB interface with a USB to PS/2 adaptor.
What I would really like is a USB (or PS/2) multimedia controller with
multiple buttons, knobs and jogwheels which can send X keycodes
(possibly MIDI based) to applications.
Some partially useful comments/questions/answers below...

Using the PS/2 interface on a PC running FreeBSD 4.5R + XFree86 4.1 I
was able to get some of the keys to work with the following in my
/etc/X11/XF86Config:
Section "InputDevice"
Identifier "Keyboard0"
Driver "keyboard"
# Option "XkbModel" "pc104"
Option "XkbModel" "itouch"
EndSection
XFree86 4.1 doesn't have "logiinetnav" support but the "itouch"
support appears compatible with some of the keys and worked for those
keys.
XFree86 4.2 should almost fully support the full "logiinetnav" model
(you may need "logicordless" as you mention above). xev will show
decimal keycodes which can be converted to hex removing bit 0x80 and
comparing with the table in /etc/X11/xkb/symbols/inet.
My laptop (running 4.5-STABLE + XFree86 4.2) works okay for the
standard keys with the USB interface using "kbdcontrol -k /dev/kdb1"
to switch to the USB keyboard. However, the extra keys don't do
anything for me either. Looking at src/sys/dev/usb/ukbd.c there
appears to be a conversion table (ukbd_trtab) which may need some work
in order to support the extra keys. I haven't closely examined all of
the code yet, so I'm not sure if there is an easy fix to just pass
through the unknown keycodes. I'll be busy for the next few weeks,
but after 4.6 is released, I may look at this further.

Any response on this? I'd like to do this also on my laptop (or even
better be able to distinguish between the two keyboards somehow).
