I checked the FAQ and didn't find an answer to this question. Some relevant snippets from the SRD:
So you can make an AoO even if it's not your turn to take action, but you don't get to act if you're surprised. Which takes precedence?
As an aside, can you take an immediate action (e.g., cast feather fall) if you're surprised?
SRD said:Unaware Combatants
Combatants who are unaware at the start of battle don’t get to act in the surprise round.

Threatened Squares
You threaten all squares into which you can make a melee attack, even when it is not your action. Generally, that means everything in all squares adjacent to your space (including diagonally). An enemy that takes certain actions while in a threatened square provokes an attack of opportunity from you.
