Inflict Damage Spells Useless?

[Lamoni]

The Inflict Damage Spells and Disable Construct from the Eberron Campaign Setting supposedly deal damage to constructs. But, they allow for spell resistance.

Since most constructs have Spell immunity, doesn't this make the spells useless?

Are these spells only supposed to work on Warforged or the few unique constructs without spell immunity? Or am I missing something?

Most constructs in my experience don't have spell immunity, just golems. There's a wide variety of non-golem constructs out there, especially in an Eberron game.
