Hi Ben and Greg,

Please consider 

 9756fe38d10b drm/i915: no lvds quirk for Zotac ZDBOX SD ID12/ID13

for application to the 3.0.y, 3.2.y, and 3.4.y trees.  It was applied
upstream during the 3.6 merge window, so newer kernels don't need it.

Alexander Kurtz writes, using a kernel closely based on 3.2.30[2]:

> The Zotac ZBOX SD ID13 has an internal LVDS connector which (at least in

Thoughts of all kinds welcome, as always.
