Since no one else has replied, I'll try...
I think you'd want to break up the large image into smaller tiles if you are wanting to draw parts of the image at 1:1 ratio (because each line of the source image contains so much info that you'll want to ignore.
With respect to the zooming, PFrog can scale, but it will just pick single pixels from the source image - not do an average of pixels, which would look a lot nicer.
It's pretty easy to make a picture 1/4 the size by averaging 4 pixels into 1. Do that twice and you'll be close to the resolution of your PDA...
