After replacement of LV8013 (motor driver + power supply for lens) my Canon 400D is repaired, error99 is no more.
On the attached image (showing layout beneath the LV8013) it is obvious that +13V is used for lens power supply (one via leads to the bottom of the power board, which I didn't have to remove to solder in the new IC).
Couple of days ago I also received the UV-IR CUT filter (Rocolax 48mm, for my Canon 400mm 2.8L drop-in adapter), so it will be possible to do some real testing tonight if weather in Melbourne permits.
Pictures attached: two at the top row are taken with same lens, with "normal" (left) and modified camera (right).
The bottom image is taken with modified camera through Rocolax UV-IR-CUT filter.
