With version 14.04 and the nvidia-331 (331.38-0ubuntu7) driver the flickering reappeared although the line is still present in options.conf.
Using modprobe --resolve-alias nvidia I found the correct driver module name which in my case is nvidia_331. Changing the module name in options.conf to nvidia_331 X doesn't start anymore. Removing the NVreg_ModifyDeviceFiles option X is starting again, but does not solve the issue.
As requested in Bug #1310633 I'm opening a new bug.
With a previous version of Ubuntu I already had this flickering. With additional options for the kernel module I was able to fix the flickering.
