According to the player of the Druid he asked about this specifically - and was told that the passage in the PHB2 was supposed to be for BONUS damage not EXTRA damage. i.e. Feats that add to damage should need a base damage to add to. Effects that add extra damage on conditional circumstances add the extra damage regardless of intial damage if the conditions are met.
The thing is, there's no 'bonus' damage, other than 'a bonus to damage.' The PHB2 text is pretty clear that it refers to -extra- damage.
