[opensuse-it] could not get italian keyboard layout working

Hello. Sorry to ask English question on an Italian list, but I guess only in here I can find the solution to my problem. My keyboard layout is exactly like this: http://en.wikipedia.org/wiki/File:KB_Italian.svg but in gnome control center if I choose Italian keyboard layout, it look like and mapped like the screenshot attached to this email. I also tried to change XkbLayout to "it" and resulted exactly the same, a.k.a. the keyboard is mapped like the attached screenshot but not the actual layout as given in wikipedia article. Question: do you have same actual layout as I have and how you manage to configure the mapping? Thanks in advance!
