--- Comment #3 from Chris Wilson <chris at chris-wilson.co.uk> ---
For starters, your xserver is broken - it is not selecting a CompatOutput() for
the headless case. The BIOS sets up a 1600x900 mode on DP1, but there is not
EDID for that panel so we treat it as disconnected. We have no means for
determining the native timings for that panel. So either the NAK we get for the
EDID probe is wrong, or the manufacturer skimped by hiding all the information
in the BIOS rather than the panel firmware. If that is so, all you can do is
hope for fastboot.
