There are more and more affordable tft displays for Raspberry Pi coming with a resistive touch panel like this from german cheapo - supplier Pollin. If you don't want to waste a USB connector and are happy to use the touch function from within Python for example via TTY, you might find this little controller helpful.
Bulky original touch controller to be replaced.
Here you have touch.zip, containing the BASCOM source for the Attiny85, corresponding HEX file, Python test program and lcd.py module containing some VT100 shortcuts. The Attiny is set to 8 Mhz internal RC clock and brownout detection for 2,7 V.
