What is output in the log closely corresponds to what is written in the configuration file. The section defines what devices are used by the X server. In this case, a mouse, a keyboard and a monitor with a GeForce 2 graphics card. There may be multiple ServerLayout sections in the XF86Config, but only the first one will be parsed.
The first line, (==) ServerLayout "Anaconda Configured" means that Red Hat's configuration tool Anaconda was used to generate the initial XF86Config file. The file may still have been changed manually afterwards. Other often seen values are "XFree86 Configure" meaning that XFree86's configuration tool xf86config was used, "Main Layout" or "Default Layout".
