--- Comment #31 from Ville Syrjala <ville.syrjala at linux.intel.com> ---
Hmm. I guess one weird possibility would be that the EDID would be at some
alternate address. I can't recall if that's allowed by the spec, but IIRC in
the distant past there were a few addresses that could house the EDID.

Please run something like this as root so we can probe the entire i2c address
range:
modprobe i2c-dev ; i2cdetect `grep DPDDC-A /sys/class/i2c-dev/*/name | cut -d
'/' -f 5 | cut -d '-' -f 2`
