Driver is the likely culprit. Can you enable 1080i output, check that it
works and grab the output of intel_reg_dumper from intel-gpu-tools. Then
please do whatever dance is required to break it, and again grab the
output of intel_reg_dumper. Hopefully there's some funky register we've
forgotten to set up again correctly.
