--- Comment #4 from Charles-Antoine Couret <renault at fedoraproject.org> ---
With default option, after boot :

[root at DiNozzo ~]# cat /sys/class/backlight/acpi_video0/brightness
20

Same conditions, after pressure of FN down brightness key :

[root at DiNozzo ~]# cat /sys/class/backlight/acpi_video0/brightness
10


I suppose the driver can write this file after that. ;)
