What is the module's actual name? Where should it be located. I didn't have a MODULE section so I created one but now it says it can't find that module. Is the file the libGL.so or is it something else?

How do I determine my Kernel version.
Try "uname -r".
For example:
uname -r
2.4.11-pre5
Do I really need to compile something into the kernel
to get this to work? Is loading modules enough?
Usually you just have to load the module. But I prefer compiling all my stuff into the kernel :)
Besides, you only need to do something about the kernel (be it loading modules or recompiling) if you want to use hardware acceleration.
Just do what Mattias told you.
You may want to redirect startx's output to some logfile and read it afterwards, i.e.: startx >x.log 2>x.err
One of the two files (x.log or x.err) will be empty because X writes everything to stderr (or stdout, respectively), but I can't recall which one :-)
Just look for something like "Direct Rendering" or "GLX". If you read "Direct rendering enabled" somewhere, hardware acceleration works; if not, then not. At least that's the case for me (XFree86 4.1.0).
Maybe it's not important (probably it is for hardware acceleration), but I also have the lines:
Load "dri"
Load "drm"
in the modules section of my XF86Config file (besides 'Load "glx"').
Also, if you want to use hardware accelerated OpenGL as a normal user (which is likely, isn't it?), you have to put this in the XF86Config file too:
Section "DRI"
Group "video"
Mode 0666
EndSection
This allows all users in group "video" to use OpenGL hardware acceleration. Or so I think ;)
You might want to create the group "video" and put yourself in it, or change "video" to "users" or something.
I don't know if you need all this if you want to use software rendering, though...
In X, you can check if OpenGL is enabled quite easily: open a terminal window and type "glxinfo".

No I didn't. I'm not sure how to do that. :-) I looked at that site
dri.sourceforge.net and it said I needed kernel 2.4.5. How do I determine
my Kernel version. Do I really need to compile something into the kernel
to get this to work? Is loading modules enough? ..too many questions.

Hi.
Have you enabled DRI/GLX in your XF86Config file and compiled DRI/DRM
support into your kernel (or installed the appropriate module)?
It took me a while to set up OpenGL support, but it works for my ATI Rage
128 card.
If your card isn't supported by X or the Linux kernel, you will have to use
software rendering (which is slooooooooooow).
For more information see
http://dri.sourceforge.net/.
