DDC is the channel by which the EDID is fetched. The xorg log should
print the raw edid. You can use edid-decode
(http://cgit.freedesktop.org/xorg/app/edid-decode/) to parse the edid
and see what's in it. If edid-decode lists modes that are not
available in kms, it's due to kms not parsing the extension blocks yet
or it's not parsing them correctly.
OK, I tried edid decode with the code from xorg log, but it displays
some junk then the same four modes that kms sees (output is below the tv
section of my xorg log which is attached).
