Are you wanting to use a pen directly on the screen or a pen and tablet like the wacom bamboo.- a digitizer that sits on your desktop that you input into with a pen?

As for a stylus and the 526 screen, it will work but not as well as it would on a tablet PC. I have seen a pen at Ooofice Max that is a three way pen, pencil and stylus. Its kind of like one of those multi color selectable pens where you click the different button for each pen. On the particular one that I have (which was made for a PDA/Pocket PC) the stulus tip is orange so you wont inadvertantly use the pen or pencil.

Since the sensor array is a group of LED's and sensors, it may pick up anything that gets close to the screen like your finger while you are holding the stylus. Unfortunately (in your case) the IQ series was designed for finger touch input. Thats not saying a stylus won't work, it just wasn't designed for it.
