What's important to take from this seemingly outdated concept is the quality of respect. When someone opens a door for someone else, it's not because they believe the other person cannot do so for themselves; it's simply good manners, regardless of the sex of the door opener or the person who walks through. Many men still prefer to pay the check on a date, and while a woman may not deem it necessary, it's still a thoughtful gesture. Modern chivalry is all about respect, and it goes both ways. Call when you say you will; don't stand up your date; show signs of affection and appreciation for one another; and don't be disrespectful, particularly in public. Be gracious when these gestures are shown to you - it's simply good manners, so respond in kind.
