Type5 keyboard with kernel version 2.6.x

[Christian Tusche <ctusche@gmx.net>]

I'm running debian-testing on my Ultra60 together with a 2.6.12 kernel. I 
wonder how to get the type5 keyboard to work with xorg. What is the right 
keyboard layout to select?
Since for the 2.6.x series kernel the keycodes get translated to a PC-style 
keyboard, i am using the "pc104" layout. This gives basic functionality, 
however the function block on the left as well as the volume keys produces 
no keysyms. The "sun" rules will not work at all, because they rely on 
untranslated keycodes.
Is there any other layout, which supports the type5 keyboard on the 2.6 
kernel?

Thanks.
