The revocation is a much bigger deal than the DUI. The DUI is ancient history at this point, and will continue to fade in significance with time. Not so with the revocation, which will be the first thing that every employer considers for the remainder of the career.

The best one can do is try. Given that the revocation was tied to to the old DUI and that it happened as a function of an inexperienced student, it will be easier to explain, but getting to the place where you're given a chance to explain will be your challenge. A lot of employers will ask if you've ever had certificate action, and once that box is checked, the conversation is over.

If you can get to a place where you're allowed to talk, or in other words, get to the interview floor, and you approach it with humility, clear evidence in your attitude that you learned and clearer evidence that you'll never do it again (learning is evidenced by a change in behavior), you'll have a shot.
