modprobe.d question

[Loïc Martin]

To support my buggy laptop LCD screen, I have to pass an option before X 
starts. At the moment, I've added the line :

options nvidia NVreg_Mobile=0 NVreg_ModifyDeviceFiles=0

to /etc/modprobe.d/nvidia-kernel-nkc

However, it appears it isn't soon enough - at start, gdm fails and I 
have to login in a text console, and either use startx or kill gdm and 
launch it again.

Does anyone knows how to make the file /etc/modprobe.d/nvidia-kernel-nkc 
used earlier at boot time? If it's not possible, where else could I add 
the aforementioned line?

Thanks,
Loïc
