In many cases, its difficult to visualize the contrast in sensor sizes only by seeing a spec sheet. The image below might provide you a better sense of the sensor dimensions in the 9000 and K20D.

Clearly, both cameras feature different megapixel count and different sensor sizes. The 9000 with its smaller sensor is going to make achieving shallow DOF more challenging and the Pentax K20D will produce extra detail using its extra 3 Megapixels. Higher resolution will also make it easier to crop shots way more aggressively. The fresher 9000 provides a benefit with regard to sensor innovation.
