Exclamation Display ignores settings in xorg.conf

Regardless of the settings contained in my xorg file, my maximum resolution is always 1024x768.
I've tried to remove the xorg.conf file and it white screens, when I do a CTRL-ALT-BKSPCI can see the screen as it should be with the wallpaper for a split second before X dies.
No problems prior to updating xorg lastnight although I cannot say for sure that is what caused this issue.
Livna repo is installed and has been working fine prior to this at a resolution of 1440x900. Any help is appreciated.

$ lspci|grep nVidia
01:00.0 VGA compatible controller: nVidia Corporation G73 [GeForce 7600 GS] (rev a2)

$ xrandr
Screen 0: minimum 320 x 240, current 1024 x 768, maximum 1024 x 768

640x480 53.0
512x384 54.0
400x300 55.0 56.0

Here is my xorg.conf file:

You haven't specified what release of Fedora you're running (F8 or F9) although I suspect F9, nor what updates were made before the change.

The whole X11/Xorg mess is still under heavy development and revision, with changes occuring constantly. A regression is really not a surprise. Most importantly, is direct rendering still working ? Check with:
glxinfo|grep render

Result will be either "Yes" or "No". Personally, I don't understand why 1024x768 isn't good enough, but I suppose if you're used to 1440x900... Please attach copy of Xorg.0.log in full. It appears that there are problems because xorg.conf specifies LCD but that snippet from Xorg.0.log says CRT....

I got it fixed finally..

After adding a modeline, I ran 'sudo nvidia-settings' and it finally picked up the change and made a modified xorg.conf for me and all looks to be ok now.

Here is my revised xorg.conf file:

# nvidia-settings: X configuration file generated by nvidia-settings
# nvidia-settings: version 1.0 (buildmeister@builder63) Thu Jun 5 00:11:12 PDT 2008

# Xorg configuration created by system-config-display
