Of course, I don't keep unused drivers.

xorg automatically depends video card and uses corresponding driver.
I don't have any problems with libGL.

Bad idea, because I'll need to create them manually, when I use nvidia card.

May be udev should create these devices? udev loads modules for kms 
drives. OK
nvidia doesn't use kms, but I quite shure, that xorg loads nvidia driver (if
nvidia card presents), not udev by accessing /dev/nvidia0 or /dev/nvidiactl,
anyway xorg loads modules for non kms drivers.
