First - 1.0-2960 is a very old driver. Please grab 1.0-4349 from http://www.nvidia.com/view.asp?IO=li...ia32_1.0-4349.
Second - your X log indicates that you're running out of valid modes. This is probably due to
(WW) NVIDIA(0): The user specified VertRefresh "40.000-150.000" has been
(WW) NVIDIA(0): adjusted to "" (the intersection with EDID-specified
(WW) NVIDIA(0): VertRefresh "176.000-50.000"
(EE) NVIDIA(0): no VertRefresh values remaining

Option "IgnoreEDID" "1"
XF86Config option (as long as you're sure the ranges you're specifying in your XF86Config file are right!).
Your GLX library appears to be loading fine.
You shouldn't load dri.
