More often than not, it is difficult to see the contrast in sensor sizes purely by going through technical specs. The picture underneath may offer you a stronger sense of the sensor measurements in the DP2s and A100.

As you have seen, both the cameras provide the same sensor dimensions but not the same megapixels. You should expect to see the Sony A100 to produce extra detail using its extra 5 Megapixels. Greater resolution will also make it easier to crop pics more aggressively. The more modern DP2s is going to have a benefit in sensor tech.
