Right, I was trying to ascertain whether the intel_lvds_ddc_probe()
correctly detected the missing panel. That function currently requires
GMBUS to differentiate between a NAK and an IO error (bitbanging just
returns EREMOTEIO regardless, iirc). So far it has been successful in
detecting one false-positive for an AOpen All-in-one and hasn't fouled
up LVDS detection for the laptops I have.
