This was my fix for AsusZ63A laptop running FC5. Interesting read before you get started
http://fedoraproject.org/wiki/Xorg/3rdPartyVideoDrivers.
Error--->i915 DRI driver expected DDX version 1-1.5.x but got version 1.4.1
libGL warning: 3D driver returned no fbconfigs.
libGL error: InitDriver failed

You should find i810_dri.so and i915_dri.so in:
/usr/X11R6/lib/modules/dri/
/usr/lib/dri/
Rename i810_dri.so and i915_dri.so located in
/usr/X11R6/lib/modules/dri/ to something like i810_dri.so.old
i915_dri.so.old for keeps sake, then create symbolic links in the
/usr/X11R6/lib/modules/dri/ directory to the ones in the /usr/lib/dri/
directory. Example:
ln -s /usr/lib/dri/i810_dri.so i810_dri.so
ln -s /usr/lib/dri/i915_dri.so i915_dri.so
Run the above commands assuming you are already in the
/usr/X11R6/lib/modules/dri/ directory.
If the above doesn't work try uninstalling and reinstalling the mesa
library then doing the above.
