The list you want doesn't exist. Basically anything that would be listed as a special attack in a monster statblock that requires a DC save would count.
Non monster wise, things like Stunning Fist often are allowed to work with it. It's an attack, it's special, and it requires a save. I would save no to something like spellcasting, though

As a thought, the PRD's section on Universal Monster Rules has a huge list of monster abilities, and many of them state whether or not they might appear in the Special Attacks section of a stat block.
Check here. I would say this is a good jumping-off point as a GM: Is the ability similar to something on this list? Then it might be a good candidate for Ability Focus.
