The "Mobile Sandy Bridge CPUs" in the Fujitsu Esprimo Q900 mini desktop PCs are probably misleading the LVDS detection code in intel_lvds_supported. Nothing is connected to the LVDS ports in these systems.

So despite that snb has a bit who's _only_ purpose is to allow the bios to tell the driver whether there's an lvds output or not, someone screwed it finally up :( We just can't win against the firmware ...
Queued for -next with cc: stable, thanks for the patch. -Daniel
