I was having a similar problem when using the nvidia-glx RPMS provided
by rpm.livna.org.  Those RPMS (wisely) install the nvidia libraries
in /usr/lib/nvidia so they don't conflict with the xorg-x11 ones.  It
also installs an nvidia-glx.conf in /etc/ld.so.conf.d so the linker will
use them.  Unfortunately, /etc/profile (at least, I think that's the
culprit) adds "/usr/X11R6/lib" to LD_LIBRARY_PATH which is consulted
before /etc/ld.so.cache when linking, meaning the nvidia libraries are
not used so you get no hardware acceleration.

Fortunately, they also ship with a /etc/profile.d/nvidia.{sh,csh} so you
can add

export LD_LIBRARY_PATH=/usr/lib/nvidia${LD_LIBRARY_PATH:+":$LD_LIBRARY_PATH"}

to make sure the nvidia GL libraries are found before the xorg ones.
