Th fact is that it should have been there I guess - I already tried 105key
and latitude but no success. when searching in google on "a4techKB21" I
found this http://osdir.com/ml/debian-bugs-dist/2011-05/msg00724.html

which is pretty similar to my problem and what I see in the Xorg log file

Yes this is correct I played with some combinations of following

Section "InputDevice"
        Identifier  "Keyboard0"
        Driver      "kbd"
#       Driver      "evdev"
EndSection

Section "InputDevice"
        Identifier  "Keyboard1"
#       Driver      "kbd"
        Driver      "evdev"
        Option       "XkbModel"     "pc105"
EndSection

in-place I did never have to reinstall. I upgraded to jessie because I
switched the notebook. The old one was already for 8y in my service. But X
in wheezy seem not to support the newer intel HD, so dilemma compile X+
packages or upgrade.
I think this should be some bug or lack of proper mapping/setting the
keyboard. This one is cheep ISY IKE 3100 USB Multimedia Keyboard, but the
bug mentioned above describes wrong configuration because detecting a power
key, which I see in the log.
The MM keys work on the latitude board and they were working in the previous
version of debian for sure.

So thank you anyway for the time! it looks like it will take some time to
fix it, though it is annoying, because I use the computer to play music, or
watch tv in the free time and it is pretty handy to control the volume via
the external keyboard.

As I'm pretty busy with business and a 2y old funny little furry so I
decided to ask the community before taking the trip into the darkest secret
places of this part of linux and X ... I never had to, but it is also never
too late.

Thank again - if I find the solution I'll update for the sake of truth and
completeness
