Have you checked to see if the issue will be resolved by using the
ELRepo kmod-nvidia package [1] ?

Yes, I have tried it. Nvidia Optimus is not supported and never will be
in Linux - official Nvidia's statement. The similar situation is with
ATI's fglrx and their switchable HD5470, which is quite common now.
So only opensource drivers with kernel > 2.6.35 (SL6 is based on
2.6.32), with vga_switcheroo
("http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=6a9ee8af344e3bd7dbd61e67037096cdf7f83289";).
As a result you will have poor 3D acceleration, higher power consumption
and no OpenCL or CUDA.
The best solution is to switch the dedicated graphic card off in BIOS.
