Laptop Fn key causes X (Gnome 2) to sleep immediately

[Matthias Petermann]

At the moment it is not clear to me at which layer the issue is  
originated. In fact the acpi_ibm module doesn't work completely for  
the Lenovo X121e (brightness control with Fn+F8/F7 nonfunctional), so  
the issue might be related to this. I shall file a PR during the day.

Kind regards,
Matthias
