jonathan_s, Not sure that I am an expert on tablets.
One of the posts confirms what you are saying:

The price of the pens in question is quite reasonable and the pen which I have works for me. It is definitely a much better pen than the original thin stylus provided by Irex.
Better contact Gateway and ask them for more information, of course if they are willing to provide any. I could not find much information on their tablets either. I remember just relying on a forum.tabletpcreview.com. forum post, which pointed that some of their models use Wacom's penabled screens. If you find anything more, certainly it would be appreciated. Also, you may want to ask for an advice on the forum.tabletpcreview.com.
Good luck
