[Joël Bourquard <joel.bourquard@xxxxxxxxx>]

It's a GT330M, the same as in prior models as far as I know...

What I don't understand is how could nvclock even work for Z models before
the Z13 ?  I mean, isn't the physical brightness control physically
connected to the Intel card at all times ?

When booting in NVIDIA mode I tried to write to those ACPI brightness
entries, I can read back the values I write, but they have no effect
whatsoever on the brightness.
