            The FAQ clarifies that movement altering, unless specific does not function in powered armor.
But I just ran into something in a society session that augments in specific slots do not function either, these being things like the feet and hand slots or things that would change physiology.
A clear one would be the thruster heels and force soles in larger armor
The thruster heels have a function that grants a bonus to the next athletics check but since they are attached to your feet within the larger armor they do not work.
RAI, I completely agree with this, it makes total sense for you to just slam into the monitor when you activate these inside the armor.
RAW however, nothing like this is noted. Not in the current FAQ either.
Things like defensive ball graft or the force bolt graft.
Can powered armor be modified to accomodate augments like lighter armor can?
Or are augments that are usable in powered limited to straight stat boosts or mental actions?

            In the context of your question, All of them that don't mess with your movement speed. They are augmentations they don't modify movement they work.
The thruster heels and force soles work. Stopping them from working is against the rules. I'm the last one to say that a rule is never unclear or a judgement call but in this case it really is. It's an augmentation, it works.
In a home game, the player and DM could easily come up with a list of things that do or do not make sense to affect the mecha while on the pilot. Your player can ask "Hey, Tanky McMechazoid is hitting the augment shop, I want to buy this, is that going to be incompatable with my Mk 45 Ankylosaur Battle Armor. In starfinder society though you're buying that stuff either on your own, or on the advice of one DM and moving around to others So that's not an option.
For a blanket rule we have what we have, society is stuck with the ill fitting one size fits all answer, which is better less bad than 10,000 different tailors working on duct tape tuxedo that is YOUR character. 
The ball works. Starfinder Armor uses tech, force fields, magic, magic force fields, regular old metal plates, and magic tech forcefields. So "its not physically possible...." needs a higher degree of leeway.

My own rule of thumb is that, unless explicitly otherwise, the absolute worst case is "your augmentation requires the armor to be modified to function properly". If you can refit armor to accommodate a completely different number of limbs or size category with fairly trivial effort, you can do the same for rocket boots or whatever other cybernetic augmentations. Which means it should only ever be an issue if your having to pop on some random suit of armor that hasn't been fitted to you, and don't have time to do the fitting work.

            [Just in case there's still any doubt, there's a FAQ entry explicitly stating augmentations work in powered armour (although armour upgrades in light armour worn under the Powered Armour wouldn't)].

            It's under the CRB FAQ entry (if it works lol)
Q. Do things like armor upgrades on light armor and augmentations function when also wearing powered armor?
A. Armor upgrades installed in light armor do not function while their wearer is wearing powered armor. Augmentations function normally.

            Effects (including abilities and spells) that change a creature’s speeds do not affect the speeds of powered armor that creature is wearing; the powered armor's speeds replace the creature's. A creature wearing powered armor can use the speeds (both type and distance) only of its powered armor.
There we go, i thought those two faqs were together.

            Despite the higher degree of leeway, the force soles in power armor still struggle in concept. The tiny fields of force energy would appear below your feet, not necessarily the feet of the power armor. Thus, unless in zero g, your character would have to maintain the weight (bulk) of the power armor upon themselves.
That said RAW, it does work.
