Disclaimer: Agnostic Atheist here.
In terms of the very definition of atheism (a lack of belief in a greater power), it is a stretch to call it a religion.
In terms of faith, I think many (if not all atheists) possess a certain amount of faith. For example, I possess a lot of faith in the scientific method. I know it is not infallible, but I do believe that it is self-correcting and will ultimately lead to a greater and greater understanding of the world. Faith does no necessarily have to be belief with lack of evidence.
I would argue, however, that the faith many atheists possess differs significantly from the faith possessed by religious folk (this might garner some argument). My faith is founded on my experience with the natural world. I take a leap of faith in trusting the methods of other scientists. Scientists are humans with flaws but overall, based on my experience, I believe the system works. Religious faith cannot be founded on worldly experience because, by definition, it deals with the supernatural (and thus un-observable). Faith in the morals of religion may be founded in experience, but the ultimate pinnacle of religion - a belief in god - is a faith that has no foundation to support it. This does not mean it is wrong. Merely, it means that it is a different kind of faith than atheistic faith.
1. Complete trust or confidence in someone or something.
2. Strong belief in God or in the doctrines of a religion, based on spiritual apprehension rather than proof.
I would argue atheist faith is #1 and religious faith is #2.
