Take a look at morphos-news.de and morphzone.org to see which name I'm talking about. And no, this is no joke, they have the connection to get it.
I would actually think that Atari themselves might be a bit reluctant, but that is just a hunch.
In case you did not know Infogrames (one of the largets game publishing companies in the world) renamed themselves into Atari about a month ago. So I really have a hard time seeing Genesi being able to use that name
