What kind of messages do you get in /var/log/messages or in the Xorg log 
when it fails? (/var/log/X11/Xorg*) Anything video related that might be 
of relevance?

Maybe 3.8.x is too old for your hardware... (video hardware, that is).

Just a day or so ago I released a 3.10.x rt patched kernel for fc19, 
maybe trying that would help?
