Failed to Initialize the NVIDIA graphics device - Samsung TV LN46A650

[moodyjunk at frontiernet.net]

I'm running Fedora 12 kernel 2.6.32.26-175 and can't get Xorg to initialize my Samsung TV LN46A650.  No nVidia splash screen, just a black screen with fast blinking cursor.  The system does boot and Xwindows is running - I can VNC in to a full GUI desktop. Here are my system details:

I tried both nvidia-xconfig and livna-config-display as the xorg.conf file shows.

My Fedora 10 system works fine to the same TV and I do recall having to do something special to get the video working but I don't recall what.  Can anyone help?
