Hi Mario,
I found the maximum value you are looking for:
0x1ff00
This is the minimum value that produces maximum brightness on my Geforce 310M (Vaio VPCCW21fx).
I was doing something wrong before.
Let me know if you need anything else.

Bug description:
I have a Sony Vaio VPCCW21FX (Nvidia 310M) running Lucid.

After I installed nvidia-bl-dkms 0.16.10, the brightness buttons showed the brightness indicator but it didn't move.
Manually writing values to /sys/class/backlight/nvidia_backlight/brightness turn the backlight completely off (the backlight only turned back on after a suspend/resume).

Then I copied sony brightness scripts from here:

... after that, using the brightness buttons on the laptop turned the screen off as well.
