To contemplate landing above this limitation, there must be a very pressing need. Hence I would expect a pilot to just land and try to make the best of it. I would not try to be cute on approach - not below Vref +5 or additive required, stick to the customary 3* slope and put it on at the aiming point. After that, use all retarding devices available and see what happens at the far end of the runway. The usual maxim applies - it's better to go off the end at 50 Kts rather than fall out of the sky at 200 Kts.
Those B767 drivers here can imagine the scenario of a 185 T departure with flap asymmetry between 5 and 1 on retraction. After the additives the Vref can be rather impressive and few B767s can dump fuel.
