They arent available with yum:
[root@bubba /]# yum install xorg-x11

I dont see any xorg packages there, am I just missing them?

Maybe you are using thewrong package name thats why you can't find them. Do,
All packages containing "xorg" will be listed.

You are using CentOS 3, which is the equivalent of RHEL3. So, naturally, you would be looking for XFree86, not xorg. When this was released, XFree86 hadn't even been forked yet.

Ah, I should have noticed that.
