It's ages sony_laptop doesn't change, it may be some other change in the

But anyway, it's a Fn key issue, not backlight control itself, right?
Can you change brightness echoing to the sysfs files directly?

can you attach dmesg output after loading sony_laptop with debug=1 and
pressing the brightness keys?
