Thanks for your help, but to do this the keys would have to be 
recognized by X already, wouldn't they? In my case, xev shows nothing. 
X does not know when the keys are pressed. The only response I get when 
I press the Fn keys are these acpi events registered in system log.

Unfortunately, this was not the case here :(  However, at least now 
something shows up in the logs, that's a progress. With F7, nothing 
happens at all when the Fn keys are pressed at this laptop.
