Sadly not. The issue in question, for readers at home, is that after

    drm/i915: Move cached EDID to intel_connector
    
    Move the cached EDID from intel_dp and intel_lvds_connector to
    intel_connector. Unify cached EDID handling for LVDS and eDP, in
    preparation for adding more generic EDID caching later.

I lose the EDID on a SDVO-LVDS device (an ilk dual LVDS and SDVO-LVDS
Libretto W105).
