The comment for the get_brightness backlight device callback in include/linux/backlight.h states that it should "return the current backlight brightness (accounting for power, fb_blank etc.)". fujitsu-laptop violates that premise by simply returning the value to which ACPI function GBLL evaluates to. Make sure 0 is returned when backlight power is turned off.
