As you used the phrase "stopped working", I'm wondering whether you were
ever able to get ACPI brightness control to work on a Haswell machine?
It seems to be broken on my Lifebook E744 (BIOS version 1.19): pressing
the brightness keys causes acpi_fujitsu_notify() to call GBLL, which
always returns the same brightness level, even though it sets the
highest bit in its return value (which denotes a brightness change).
Also, calling set_lcd_level() with various values causes the value
subsequently returned by GBLL to change, but the actual screen
brightness is identical all the time.

It looks like it is handled purely in hardware because I'm not getting
any scan codes or ACPI events either on a Lifebook E744 and the hotkey
works correctly.
