Yes, that is true. What I meant was, that I have everything up to date 
regarding Gentoo, except the Kernel (because it was quite a fight to get it 
to work with my system / motherboard and I am weary to do it once again).

Well, 2 reasons:
 - The joystick documentation in the kernel suggest this way
 (Documentation/input/joystick.txt)
 - The device does not work ("No such device" error). BTW, Gentoo was
 configured to tar the device files.

Thanks, I will do this, I only looked for joystick related docs, but was to 
dumb to look for udev docs, too.
