Dreamspeaker and Slumber

[SuperUberGeek]

Does dream speaker effect the slumber hex or does it only work for spells that cause a sleep effect?

I've been unable to find any clarifications on this, but my personal opinion is that by RAW, it would not affect slumber hex:
"Elves with this racial trait add +1 to the saving throw DCs of spells of the divination school and sleep effects they cast."

The relevant word here is "cast". You don't cast hexes, they are supernatural abilities you use, and things like SR and magical immunities don't apply to them as they would for something you cast. If it had said "use", then by RAW it should apply, as Slumber is definitely a sleep effect.

I was thinking the same thing.
In the creating a race section it says this:

Dreamspeaker (2 RP): Prerequisites: None; Benefit:
Members of this race gain a +1 bonus to the saving
throw DCs of spells of the divination school and spells
that produce sleep effects that they cast. In addition,
members of this race with a Charisma score of 15 or
higher may use dream once per day as a spell-like ability
(caster level is equal to the user’s character level).

It seems like it's spells only. But look I am not sure how it carries over to supernatural abilities.
