If I understand your post correctly there is nothing to "re-negotiate" since at this point there is no established company. The way I see it, you can legally do whatever the heck you want, you can even decide to go solo, you wrote all the code and have full ownership of it. Now, if this is someone you want to remain friends with it's different :) What you suggest is very reasonable, you can give him some equity in the entity and maybe allow him to seat on the board, and if it is clearly understood by all parties that he won't contribute anything past the original idea I don't see how that would be a problem.
