Thanks for trying this. But actually, just pressing the function keys is
somewhat too high level. Can you please also try to load the driver and
inspect its output in the kernel log? After installation (btw: you can
install both but nvidia_bl, if present, takes precedence), just run:

$ sudo rmmod mbp_nvidia_bl
$ sudo rmmod nvidia_bl
$ sudo modprobe nvidia debug=1
$ echo 512 | sudo tee /sys/class/backlight/nvidia_backlight/brightness

Or try some other values. And send me the output or post here. Thanks.

Bug description:
Hi, 

I'm trying to install mbp-nvidia-bl-dkms 0.24.1-jaunty on my MacbookPro 5,3.
It looks as if it's referencing a non-existent field in "struct backlight_properties"...
