Correct. EM extensions exist since v1.3. But implementation before Gen2
switches relied
on proprietary device specific mechanism (tsi57x). Addition of Gen2
switches just 
pushed forward the standard implementation. The RIO standard methods may
be used on 1.3 switches
(tested on tsi57x) as well as the standard routing table operations that
have been added
in our patches for 2.6.35.
