I could see console output, but nothing from X.

Looking at Xorg.0.log told me that the problem was the refresh rate
that was set to 50 Hz, which wasn't acceptable to my monitor.

Creating following xorg.conf solved the issue:

Section "Device"
    Identifier  "Configured Video Device"
    BusID       "PCI:240:16:0"
    Driver      "nouveau"
    Option      "Monitor-TV-1"  "Configured Monitor"
EndSection

Section "Monitor"
    Identifier  "Configured Monitor"
    Option      "Ignore"        "true"
EndSection

Section "Screen"
    Identifier  "Default Screen"
    Device      "Configured Video Device"
EndSection

This disables the non-existent TV output and allows the driver to use
suitable frequency values instead.

BTW, how did you get around it, David?
