Sorry, I was wrong. The EDID error came from a later EDID read.

I applied some further changes, including the same analog DDC fallback
in intel_ddc_get_modes(), and now I can see that a 1680x1050 mode
(which is also the native resolution of my LCD) is added in
add_detailed_info().

However, I still got this message when loading i915.ko:

[drm] TV-10: set mode NTSC 480i 0

No messages about other connectors.

Is this because the driver thinks that this is a TV-out connector (the
Mac mini has only the DVI connector, nothing else)?  If yes, any hints
how I can stop the driver to use TV modes?
