actual code from script ( i'm not the best programmer.... so if you have some good changes please post )

----------------------------------------------------------------
#!/bin/sh
i=5
while [ i$ -lt 10 ]
do
echo 160 >/sys/class/backlight/acx565akm/brightness
sleep 1
done
------------------------------------------------------------------
so if you want to try it.
as for /etc/mce/mce.ini just remove the 'filter-brightness-als' from 'Modules=', of course rember to backup original 'mce.ini'.

Just a warning: edit of 'mce.ini' and reboot, will make your screen very dark since brightness step 5 (max setting) will have a value of 12 instead of orig value of 255.
