You're looking for word-break:break-all; - only problem is it doesn't work in Firefox or Opera.
Why not word-wrap: break-word; (although not strictly standards compliant) as Fotiman suggested initially? Doesn't this do the same thing (at least in this instance) and provide cross-browser support, including IE6+? Or am I missing something, what is the real difference between these properties?
