I was laid off from a state university about a year ago, along with the rest of my IT department; about 27 people. They gave us four weeks' notice that we would no longer be employed there, and asked us to help transition to the new support system. Fortunately for that university, we are a bunch of good, honest people; otherwise, we could have wreaked anonymous havoc across the board. Personally, I think your company was wise in revoking your access, just as a failsafe. A better use of your skills and time than using you as a chairweight would be to have you train your replacement (if they have one).
