While I've never analysed the crawl in detail myself, there were many theories posted on the forum in 2006:
1. The crawl is completely new and CG (the text looks stable when compared to the starfield).
2. The crawl is original but has a fake gate-weave added (maybe to match the rest of the movie, which is from from the laserdisc master).
3. It's the real deal.
The situated is confused because, as TServo mentioned above, the GOUT trailer was shown to have a fake crawl.
