Wacom publishes APIs and sample code for integrating with them. Judging by the examples, it should be fairly straightforward to inject the requisite structs.
Yea I went through a few examples they had before making this thread, it does seem fairly straight forward, but I wasn't sure that PS even uses the wacom api. I mean it supports a whole range of tablets by various manufacturers so maybe they're using some windows API as a cover-all.
@Servant of the Lord, hmm, that probably would work, I'm going to look into it if using their native API won't work.
I kind of wanted the easiest method, hence why I'm even using photoshop in the first place. It's not too difficult to write a simple barebones drawing program, but I want this project to get done in a less then a week so looking to save time anywhere I can. Thanks for the suggestions never the less, I will try the wacom's api and see where it takes me.
