This is about the sensiblest post ive read on the matter. Fact is that Malbranque did stick his leg out, was no where near the ball and there was contact. Ronaldo was moving at high speed and it was a debatable penalty, whereas some penalties are definite dives, ie Zokorra Spurs v Portsmouth earlier on this season. It may have been a dive but ive seen worse, even from our own players.
