I've had bad experiences with it in the past due to poor performance. IIRC there is no configuration tool for it. Redhat expects that the default configuration is all you will need and if you need something different you're supposed to write your own xorg.conf file from scratch. The nvidia driver at least comes with nvidia-setting and nvidia-xconfig tools.
Try a newer kernel with the Nouveau driver; that will exclude bugs in the proprietary driver as a possible cause. If it crashes too, then there are either bugs in both drivers or hardware issues (and I would suggest the probability of a hardware fault is raised if there are similar crashes in two independently written drivers). I understand that kernel developers will be less willing to help you if you're running a proprietary driver, so you should now perform the testing that they'll probably ask you to do anyway when you report your issue later on.
