If Alastair has an intel GPU as well, an "easy" way to check if the
frame packing modes of those TVs work would be to use the testdisplay[1]
tool of intel-gpu-tools.

Shameless plug: http://damien.lespiau.name/2013/10/hdmi-stereo-3d-kms.html

Towards the end of the post, there are test display usage examples to go
and test FP modes. Mind you, people have been trying to make
intel-gpu-tools run on any DRM driver when possible, not sure how far we
are with that though.
