This isn't a normalization tool per se, but you might be interested all the same....

Object-Role Modeling (ORM) models objects playing roles in fact types that are "elementary", or, in other words, functional dependencies. Thus, you could use an ORM tool to enter your functional dependencies (fact types), supply a few constraints to describe the relationship between the object types in each fact type, and generate a normalized RDBMS schema (using, say, Visio or the now free VisioModeler/Infomodeler).

Hope that helps,
Scot.
