Brightness control works before the OS is loaded. i.e. I can use the Fn keys to increase/decrease brightness at the bios screen before the OS loads. If I do increase it to 100%, the OS decreases the display brightness around the time the acpi video driver is loading. You're right, it's clearly unrelated and independent of X.
I don't have access to the laptop right now but I'm pretty sure there's no brightness settings in the bios. Will confirm and attach logs later.
