[Ricardo Obregón <robregonm@xxxxxxxxx>]

I've tested the module on my Asus N53Jf and worked like a charm. I use
Chakra Project (KDE 4.6, Kernel Linux 2.6.38, nouveau 0.0.16, DRI 7.10)

Finally I can use nvidia driver on Linux.
My question is: if I want to go back to Intel card what is the "quick "way"?
Disabling nouveau module from MODULES in rc.conf?
