I definantly disagree with this.the standard for computer software is that 
page up/down move you one visable page (i.e. one screen worth) at a time, 
not the mount that would fit on one piece of paper at a time (some 
software will overlap the pages by moving a line or two less than a page)

try this with any existingpdf reader or any word processing software and 
you will see them working the same way.

the OLPC software should not be any different.
