As far as I can see in the .2da these are all the extra feats included in PotM (not counting tools such as Examine Object or Save Character, that are technically feats as well):

Greater Skill Focus (Skill)
Type of Feat: General

Use: Automatic.
Warding Guesture (Race)
Type of Feat: General
Prerequisites: Wisdom 11+, Charisma 11+
Specifics: At some point in the past, a relative or friend taught you a simple folk gesture to keep the minions of evil at bay. Though you rely on this superstition reflexively, unnatural creatures are genuinely fearful of you when you brandish such a sign. Whether this is because of its occult power or simply your belief in its power is uncertain.
As a standard action that provokes an Attack of Opportunity, you can make a simple gesture. Treat the gesture as a passive gaze attack. Creatures of your chosen type must make a Will save (DC = 10 + 1/2 your character level + your Charisma bonus) if they view the gesture. Failure to make the Will save results in the creature acting as if the under the effects of a fear spell.
Use: Selected
Detect Evil
Type of Feat: Supernatural
Prerequisites: Paladin Level 2
Specifics: By concentrating for up to 3 rounds, you may discern the location of nearby chaotic auras.
Use: Selection
Inspire Courage
Type of Feat: Supernatural
Prerequisites: Paladin Level 2
Specifics: You inspire nearby allies granting them a +4 bonus to Will saving throws versus fear.
Duration: 1 Turn/Level
Use: Selected
And I think that's it. I didn't add the different combat modes because those are granted automatically to all characters, and I didn't add any original feat that might have been modified, because I don't know if that's the case for any of them.
Cheers!
