Default Re: Twinview not working and nvidia-settings crashing on T61 (Nvidia Quadro NVS 140M)

I'm experiencing the same problem, but I have made some progress. I have the T61 6459-CTO. My external monitor is a Samsung 226cw LCD and I want to use it as a clone of my laptop's LCD. Its native resolution is 1680x1050, the same as my T61's. If I use nvidia-settings and click "apply", it works perfectly. If I save the changes to the xorg.conf file and restart X, the computer hangs.

Experimenting with different settings, I tailed the output of /var/log/Xorg.0.log while using nvidia-settings, I see it write this line:
(II) NVIDIA(0): Setting mode
(II) NVIDIA(0):     "CRT-0:1680x1050@1680x1050+0+0,DFP-0:nvidia-auto-select@1680x1050+0+0"
Restarting X with settings above will cause PC to freeze. However, if I disconnect the monitor and then edit xorg.conf to have a smaller resolution on the Samsung than 1680x1050, it works fine... but with panning (move cursor to right, monitor slides over). Obviously not ideal but at least its working now.

Here's the snippet of my current xorg.conf:
Section "Screen"
    Identifier     "Screen0"
    Device         "Videocard0"
    Monitor        "Monitor0"
    DefaultDepth    24
    Option         "TwinView" "1"
    Option	   "TwinViewOrientation" "Clone"
    Option	   "DynamicTwinView" "true"

    #Option	   "metamodes" "CRT-0:1280x1024_60@1680x1050+0+0, DFP-0:1680x1050_60@1680x1050+0+0"
    #Option	   "metamodes" "CRT-0:1400x1050_60@1680x1050+0+0, DFP-0:1680x1050_60@1680x1050+0+0"
    Option	   "metamodes" "CRT-0:1400x1050@1680x1050+0+0,DFP-0:nvidia-auto-select@1680x1050+0+0"

    #Option	   "metamodes" "CRT-0:1680x1050_60@1680x1050+0+0, DFP-0:1680x1050_60@1680x1050+0+0"    
    #Option	   "metamodes" "CRT-0:1600x1024_60@1680x1050+0+0, DFP-0:1680x1050_60@1680x1050+0+0"
    #Option	   "metamodes" "CRT-0:nvidia-auto-select@1680x1050+0+0,DFP-0:nvidia-auto-select@1680x1050+0+0"
Anything above 1400x1050 freezes the computer hard and the logs give no indication. I'd be happy if I could somehow script nvidia-settings on login to automatically set the monitors up without modifying xorg.conf.
