Basically, you need to go on rpm.livna.org website to download a package named livna-release.
That package will install livna repository then you will need to use the command
yum install kernel-modules-nvidia
yum should be able to handle nvidia-glx dependancy. If it does not know, use the command
yum install kernel-modules-nvidia nvidia-glx
Once you install it, press CTRL+ALT+Backspace to start hardware accelerator.
The advantage to use livna method is you don't need to touch xorg.conf and switch to console mode.
Remember that each time you update you kernel, you will need to manually update the kernel-modules. Probably in the future with the modularisation of X11-xorg, installing a driver will be easier.
