Samsung 90X3A Fn Keys

[Ian Coleman <coleman.ian@xxxxxxxxx>]

I am trying to get the Fn+F7 and Fn+F8 keys working on my Samsung
laptop, model 90X3A. These map to 'keyboard illumination down' and
'keyboard illumination up', which sets the brightness of the LEDs
behind the keyboard.

I have started a thread here
http://ubuntuforums.org/showthread.php?t=1751914 about this issue

I have managed to get the scan code (0x96 and 0x97) to respond with
the correct key code (kbdillumup and kbdillumdown) when I run
/lib/udev/keymap -i input/event4

However the keyboard backlight level still does not change when these
buttons are pressed.

According to /usr/share/doc/udev/README.keymap.txt.gz, step 6 says I
should email this list with some info as listed below.
> 6. Send the system vendor/product names, the key mapping from step 2,
>  and /tmp/udev-db.txt from step 4 to the linux-hotplug@xxxxxxxxxxxxxxx mailing
>  list, so that they can be included in the next release.
