I don’t think it’ll be the same as the J13S. However, most of the Twinhead laptops seem to have the same or similar hardware, so the XP drivers for some the F11Y or J13S hardware may work on the 12NB5800. If you’ve still got Vista installed, try running some sort of hardware profiler (like SiSoft Sandra) to get a full list of the exact hardware the machine has. You may find that most of the components are generic and the drivers can be had from the parts manufacturer rather than direct from Twinhead. e.g. if the webcam is an Intel-made model, Intel themselves may provide an XP driver.
