--- Comment #1 from Ilia Mirkin <imirkin at alum.mit.edu> ---
Does your dmesg log have a line like
[drm] ACPI backlight interface available, not registering our own
If so, that means that nouveau is skipping its backlight registration. There's
some boot parameter that will force the acpi one to not register...
acpi_backlight=vendor or something along those lines.
