My Canon Rebel XT is supposed to have a 3456 x 2304 pixel sensor, and that's what I get from Adobe Camera Raw and the Adobe DNG converter (ACR 3.1 with Photoshop CS2). But Pixmantec's RawShooter premium 2006 gives me 3470 x 2310 from a .CR2 raw capture. It's not much, an extra 53,076 pixels or 0.67%, but it is extra for free.
