Спасибо, картина проясняется. Карта когда-то покупалась именно по двум
условиям - "чтобы нвидиа" и "чтобы видео-вход".
На плате физически присутствует чип Philips SAA7114H
Я построчно ещё раз прочитал вывод lcpsi, никаких упоминаний
относящихся к видео кроме приведенного не обнаружил (если, вдруг,
кто-то сможет ткнуть носом, lcpsi -v > аттач ).
Теперь надо выяснить кто в ядре заведует общением с этим чипом.
