fiferboy, pressure information is available through the xsp x extension, the wiki is out of date and the information may not be totally correct (offsets were wrong for my device), but you should be able to boil this down into something you can use. https://wiki.maemo.org/Using_touch_screen_pressure_data liqbase makes use of this and it gives pressure readings from "are you touching me?" to "MEDIC!" so I know it works.
