char-major-195 is a reserved kernel major number for the video device.  
The kernel will see this alias entry and know to load the nvidia module 
name you specify there.  The config I supplied is from a FC6 install, so 
it may use a different module naming scheme.  You may not need the 
"-1_0-9755".  Depending on how you installed the driver, you can 
probably get away with just trimming those entries down to say 
"nvidia".  What really matters is the options line that passes the 
parameters to the driver when it gets loaded.

Cheers,
Mark
