If I add those lines to intel_vbtn_keymap and remove the two special cases for 0xCC and 0xCD, it does work, but only if I explicitly call input_sync(priv->input_dev) after sparse_keymap_report_event() otherwise i don't get the event (cheching for instance with evtest) until a sync gets called (i tried to put the sync only for 0xcd and in that case i get both 0xcc and 0xcd when i go out of tablet mode) -- Marco Martin
