We do not enable stereoscopy on older hardware in case there is some older board that still has HDMI output but for which we have no logic for setting the Vendor InfoFrame. With this, I get an obvious 3D output when using the "testdisplay" program from intel-gpu-tools with the "-3" parameter and outputting to a 3D-capable HDMI display, for all available 3D modes (be they TB, SBSH, or FP) on all four G80+ DISPs.
