Apart from the 8 instead of 15 steps, not really. But regarding this, I noticed 
something strange however. It seems like increasing or decreasing the 
brightness is done by two steps instead of one, that is when you compare it 
with the initial 15 steps you got. This means that when you start at maximum 
brightness (15) and you start dimming to zero, you got 15 - 13 - 11 - ... - 3 - 
1 - 0. But when you increase the brightness once you reached zero (which is 
absolutely dimmed), you got 0 - 2 - 4 - ... - 10 - 12 - 14. As 16 is not a 
valid value, the maximum brightness you got is 14 instead of 15.
So although the 0.25.1 version does support the MacBook pro better compared to 
0.25, version 0.24.3 is still more accurate.

Bug description:
After updating mbp-nvidia-bl-dkms 0.24.3~lucid to 0.25~lucid, backlight control 
is broken on MacBook Pro 6,2.
- Control keys to adjust brightness do not work anymore
- When unplugging the MacBook Pro from its power supply, the backlight is 
completely dimmed. Re-plugging the power supply restores the brightness to the 
value as it was before the laptop was unplugged.
- When the laptop is disconnected from its power supply and is booted, screen 
brightness is normal but not adjustable.

Running Ubuntu Lucid 64bit with generic kernel 2.6.32-25-generic.44
Using NVIDIA current drivers (195.36.24-0ubuntu1~lucid)
nvidia-bl-dkms is not installed as the backlight is steered by the Intel 
graphical adapter on the MacBook Pro 6,2
