Hi Chris, have you updated this patch? I have an Intel D525 (Pineview) system with HDMI port connected through an LVDS converter. The "panel timings" are the HDMI output mode, and it gets set through a BIOS option making it impossible to use the native resolution on the HDTV display.
Can you please attach the EDID for the connection and let's see if there is any tell-tale?
Unfortunately EDID doesn't seem to be making it through. /sys/devices/pci0000:00/0000:00:02.0/drm/card0/card0-LVDS-1/edid is empty so I tried read-edid, but it reported "Monitor and video card combination does not support DDC1/2 transfers". EDID was present using VGA-DVI so the TV does support EDID. (Although it didn't actually support the modes it claimed to when it determined it was connected to a PC!)
I've attached dmidecode output in case it helps.
