8.5 x 11 inches = 612 x 792 pixels @ 72ppi (~0.484 Megapixels)
The Lens of the cam is the most important part, not the megapixels.
Now, let's blow that up to really high ppi. 200ppi. This is the photo printing quality, I think.
8.5 x 11 inches = 1700 x 2200 pixels (3.74 Megapixels)
So, what's the megapixels we need to print on a 5x7 photo?
5x7 inches = 1400x1000 pixels = 1.4 megapixels
Realistically, you wouldn't want to print anything larger than a credit card size from the pics you mess around with in the DSi.
Credit size = 86 x 54 mm = 677 x 425 pixels @ 200ppi = 0.287725 megapixels
Okay, I am done doing math :)
