In many cases, its hard to picture the gap in sensor sizes merely by looking through technical specs. The image below will give you a much better sense of the sensor dimensions in the E-510 and S1R.

As you can tell, both cameras enjoy different megapixel count and different sensor sizes. The E-510 having a smaller sensor is going to make shooting bokeh more difficult and the Panasonic S1R will result in more detail because of its extra 37MP. Higher resolution will help you crop pictures far more aggressively. The more aged E-510 will be disadvantaged when it comes to sensor technology.
