[ Still trying to get it to work :-( ]

I'm afraid the above instructions aren't detailed enough for my little head.

IIUC, "start with the ATOMTvOut option and the tv disconnected" means
I should start with

        Option          "ATOMTvOut" "TRUE"

and with the DVI->video adapter disconnected.  What about the other options:

        Option          "AccelMethod"   "EXA"
        Option          "TVDACLoadDetect" "off"
        Option          "TVStandard" "ntsc"
        Option          "ForceTVOut" "true"

Then comes: "Then force tv-out on using driver options or xrandr".
Now I do not know what that means.  I don't think I have much control
over driver options once the X server is started, and I see nothing in
xrandr that would allow me to "force tv-out" in xrandr.

Finally: "finally plug in the tv", I guess that means to plug both the
DVI->video adapter and the TV, right?
