We've probed the VGA card all around, and even suspected one of the chips to be dead... But as it turns out, our tinkering made the card working. "Have you tried disassembling and assembling it back" approach, with thorough washing from the corrosion, helped.
The complication with the debugging was caused by the fact that VGA D-SUB works only when turned on from DOS.
