Can't install German-Apple-Aluminium Keyboard GNOME/TERMINAL

[IceRain]

Seasons Greetings dear Gentoo Crowd,

I still have some issues with my brand new gentoo install which I am quite proud of. But there is still some work to do, for which I need your help.
First Issue:
I fail to set my keyboard right. I have Apple-Aluminium attached to a normal PC. The keyboard is the one in this picture:

But whether my attempts to do the settings in the terminal nor my settings in the GNOME GUI were successfull.

Under GNOME the closest setting to my own keyboard I could find is this one:

As far as I know all relevant settings in the kernel are activated. (I read a fiew threads trying to deal with this problem)
So far I found nothing really suitable to solve my problem.
