I cannot make this work on a Kindle Touch, using either the <mbp:nu> approach or the prepended linked special space character trick (Kindlegen V2.5 under Windows). I don't have any other Kindle devices to test it on.
I know it can be done, as I can see it in the Ben Goldacre Kindle book "Bad Pharma" (free sample available). Really frustrating, as I think the ToC does look much better without underlines.
