The first thing you'll need is a Dr. Bott DVIator or Apple DVI/ADC adapter in order to convert from DVI to ADC (and power the display). Secondly you'll need to find some way of converting the iBook's VGA signal to DVI...while I seem to recall that there are VGA -> DVI converter boxes, they are neither cheap nor easily available. You'd be much better off just buying a cheap VGA LCD.
