Most hexes are (SU) supernatural abilities... so the question is moot.. Hexes generally by-pass Spell resistance altogether.
"Supernatural Abilities: These can't be disrupted in combat and generally don't provoke attacks of opportunity. They aren't subject to spell resistance, counterspells, or dispel magic, and don't function in antimagic areas."
The DCs are Saving throw DCs, which are not "Caster level Checks" so, No, the Elven bonus does not make the Hexes more difficult to save against.
