I have just added knitr processor for Rnw files to the trunk. That is,
there is a customizable ess-swv-processor variable, which, if set to
'knitr, makes "M-n s" to knit instead of Sweave, and "M-n T" to purl
instead of Stangle.

There are also specialized ess-swv-knit and ess-swv-purl bound to "M-n
r" and "M-n u" exactly as in the above add-on by Simon Potter.

Will be available in a patch release pretty soon.

This functionality is unfortunately delayed, but will be available in
the next version of ESS.

    Best,
