Got some black screens, but now I realise this happens whenever I run
"Xorg -config -retro" and then Ctl/C. I MUST reboot after I get this
message "NOUVEAU(0): failed to destroy server context" - if I try an
different mode I lose the entire display, including the text-mode
console session. I guess that is a nouveau bug, but I haven't found it
reported with a quick search. I'll worry about it later.

The good news is that I've significantly improved the screen image with my new modelines. The most simplistic:
Modeline "2048x1152_60.00" 197.97 2048 2184 2408 2768 1152 1153 1156 1192 -HSync +Vsync
... gives me perfect automatic vertical alignment. The image aligns against the right margin perfectly (it always has), but now the left black margin is about 5 mm (it was more than 20 mm with the EDID modes).

I am confused by the sync polarity. It doesn't seem to matter that I
used the gtf mode with H-/V+, even though the spec says I should use
H+/V-. When I did another test with the 59.9 Hz mode, I actually coded
the sync polarity as H+/V-, but there was no significant difference in
appearance.
