Please try the kernel at the link below. I think this should get you a samsung backlight and eliminate the acpi_video one. After booting to this kernel please verify that samsung-laptop is loaded, that you have /sys/class/backlight/samsung and no longer have /sys/class/backlight/acpi_video*, and that the Fn keys work for adjusting the backlight level.
