It could just be a joke, for all we know. People screw up Wikipedia for humor as well. My reasoning is that he wants to add a big achievement to his credentials and he's using the Chrome OS fiasco as leverage. He's trying everything to get recognized, even illegitimate means (such as defacing Wikipedia). Why he posted that on the Star Wars page, I haven't the slightest clue. But it's safe to say he does want to get recognized. Some people are egoistical (speaking hypothetically here) and even if they've failed at something, they want to get recognized for it regardless of others who may even have contributed exponentially more to a project. It's a form of psychological catharsis for failure. It's happened to me before.
