It seems to me that faith is trusting in something. We trust that the Bible is the word of God, that God was able and willing to communicate to us through writings of the prophets and apostles (and other prominent Christians of the day) - so faith is an assumption about what the Bible is, and what it teaches.
So, when Paul wrote "with the heart man believes unto righteousness," he is talking about assuming that Christ has delivered us from the nature of sin (that is, the principle thereof), which is the same as using our imagination to reach out to God for making us righteous. If we are in Christ, then we are reaching to God with heart-faith for righteousness. And since deliverance from the sin principle is ongoing in this life, we continue living this heart-faith.
"With the heart man believes..." - meaning that we actively imagine God helping us live at all times. So God is with us at all times, and not someone "out there, demanding we do things by our own strength and willpower". So the ethical commands aren't "do this or be condemned," but rather "Christ has done so much for us, that we are so grateful as to love Him with all our heart, to do whatever He says.
"...unto righteousness" - so that our right standing with God is not merely a position in Christ, but is an active and vital role that God is producing right living through us. And here is James also using the idea, since he says "faith without works is dead." He is emphasizing that the right kind of faith is that kind which obeys Christ's command to love others in a practical way. Yet, when he says "faith without works," he is stooping to the level of the gnostics (or whoever is claiming to have faith in the wrong way) in his usage of the term, in order to distinguish between the claim of faith and actual faith in Christ.
And we can see the same idea taught by the writer of Hebrews (a third witness) when he wrote about those people who died in the wilderness of Numbers, saying about their unbelief "they did not mix what they heard with faith." (Heb. 4:2 - I come to this paraphrase after comparing different translations). He uses the term faith in the same manner.
So what James is writing against is the idea that someone having faith in Christ can do just anything they want (namely practice class prejudice) and still be saved. He is saying that's not real faith in Christ, and that's why it's "dead." Someone having real faith is going to love their neighbor in the same way that Christ does and commanded us to do.
This is the only kind of faith that makes "sola fide" correct in the Biblical framework. It's the only kind of faith that measures up to what the whole NT is about.
