do you think a single page like that is enough to pandalize an entire site
It doesn't seem likely - at leaast I haven't seen any examples. That's mostly because once a webmaster finds success with one page they are very likely to extend the same tactic to more pages.
However, if that one "SEO text" page was successful before Panda and was ranking well for a competitive query term, then it might happen. The site sort of stuck it's head up too far and that volunteered it to be shot down. We still only see the outlines of Panda in a fuzzy way and may never have a lot of precision, so I'd hesitate to claim a definitive answer.
