Telling your supervisor how to do his job (supervise, or rather, interface with the higher ups and ensure the deadlines are hit) is a good way to paint a target on your back. If your work is good, let it speak for itself. Make yourself heard through your ideas, your additions to the team, and your quality of work. If you can't, find a job that appreciates your talent try harder. The economy is slowing down, corporate entities are seeing it as an excuse to clean house. There are four categories that go first in this case: The New Guy, The Noisy Guy, The Useless Guy, and The Coaster. It's impossible to control the first, easy to control the next two, and easy to fall into the last. If you have good ideas, but also show the respect to seniority and authority that makes a manager want you to be under him instead of under a supervisor that's under him, you are more likely going to get promoted.
That's my take.
