Oftentimes, its difficult to picture the difference between sensor sizing merely by reviewing technical specs. The visual here will help provide you a clearer sense of the sensor sizing in the K-x and K100D.

As you can tell, both cameras feature the identical sensor size but different resolution. You should anticipate the Pentax K-x to offer greater detail having its extra 6 Megapixels. Greater resolution will enable you to crop pics way more aggressively. The newer K-x provides an edge when it comes to sensor innovation.
