Text without a backlink should theoretically be enough to remove any bad signals caused by the page. But Google has a long memory, so you could be in for a long wait before the association disappears. To be blunt, if you offered another site content, and they want to keep it, I would say that's up to them!
If you're asking whether or not this will be enough to fix your ranking problems, then I would recommend you head over to the "Cleaning your backlinks" thread: [webmasterworld.com...]
