And what has the dsp to do with the touchscreen? Where did you get that information from?

I was under the impression that the dsp is used to filter the presses to determine stylus vs finger and to focus the X Y coordinate. Is the touchscreen driver open?

It's a kernel driver, look for tsc2301.c and tsc2500.c

Try re-flashing. Always works for me.
