Thanks for your answer and sorry for the delay. I finally got some time to look into this: When I boot with the named boot option the key does work with and without fujitsu_laptop being loaded. Additionally I found a bug report at launchpad: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1159690 with some more people affected by this, who are using notebooks from different manufacturers, so this doesn't really seem to be related to fujitsu_laptop module, does it?
