I know what eager loading is, and how FuelPHP's ORM does it. It's my ORM.

Looking back at your example, I think the issue is that you used FALSE as third parameter on the include_related().

This MUST be TRUE, as it will prefix the columns in the join by the relationship name. Which is required, both to prevent column name collisions (to make sure all columns are present in the result), and to allow Datamapper to figure out which column in the result belongs to which object. In a complex include_related(), you could have 6 columns in the result called 'id'...
