I sort of solved this, but not quite happy with how it's done.

Quoting xorg.conf(5): "Specifying video modes is optional because the 
server will use the DDC or other information provided by the monitor to 
automatically configure the list of modes available."

Further, "When modes are specified explicitly in the Monitor section 
(with the Modes, ModeLine, or UseModes keywords), built-in modes with 
the same names are not included."

So according to this, removing the explicit ModeLines should give 
priority to the DDC-provided modes. But - the "PreferredMode" or 
Subsection Display Modes list will _NOT_ make use of these DDC modes,
leaving me to having to explicitly specify the ModeLine for 1360x768 
(at least that dose work).  That is _bad_.
