Nvidia problems

[andrew]

I have been trying to get some nvidia drivers working with fedora 5 and 
having a heck of a time.  I have installed gcc, xorg-sdk, kernel-devel, 
and ran updates on everything (including the kernel).  When I try to run 
my game (tux racer) I get this error

Xlib:  extension "GLX" missing on display ":0.0".

My xorg.conf is using nvidia for the device driver and I have Load "glx" 
and Load "dri" in my modules section (among other things).  Here is the 
odd part and maybe this is the root of the problem but I had to symlink 
/usr/X11R6/lib/modules/drivers/nvidia_drv.so to 
/usr/lib/xorg/modules/drivers/nvidia_drv.so to just get X to start up.  
But still no glx support.

Thanks for your time
Andrew
