Yeah, they had these values in the vendor tree.
Here is a photo of this beast:

As you can see I marked only 6 keys on the image.

The key "O" I haven't been able to provoke by poking around
but the vendor driver handles this, maybe something from an
earlier or alternative hardware revision?

KEY_W is indeed WPS, I will change that to the right keycode.
