Obviously that portion of the novelization has been rendered non-canon, paving the way for a more faithful version of Amadeus to be introduced down the line.

It’s worth noting that in The Incredible Hulk novelization, Martin Starr’s character is named Amadeus Cho, who in the Marvel comics universe is a young Asian American man who is one of the smartest people on the planet and succeeded Bruce Banner as The Hulk in recent years.
