A Laptop from Japan

Hey, I just got this laptop from japan, it runs on 1280 x 600 resolution. Now it's running on Windows ME, which is pretty stupid. Does anyone know how i can get that 1280 x 600 resolution on XP pro? When i installed XP earlier onto it, things look all squished up and stuff cuz it's running under standard windows 800 x 600 res. And none of the choices in the standard XP have a wide screen solution. Maybe theres a widescreen program out there? Please help
