It's not possible to use the touch panel as a Linux mouse with this adapter. The Touch IC is not wired to the Raspberry Pi SPI bus.

This shield has a joyswitch, and it can be used as a mouse or as a "keyboard". Since the shield doesn't have pullup resistors, we use the internal ones.
Mouse
sudo modprobe gpio_mouse
sudo modprobe gpio_mouse_device pullup polarity=1 up=23 down=17 left=18 right=27 bleft=22
FRAMEBUFFER=/dev/fb1 startx
Ref: gpio_mouse_device
Keyboard, arrow keys and Enter key
sudo modprobe gpio_keys
sudo modprobe gpio_keys_device pullup active_low keys=23:103,17:108,18:105,27:106,22:28
Ref: gpio_keys_device
This keyboard can be used with AdvanceMAME. Set in advance.rc
device_keyboard raw
Ref: MAME
Add to /etc/modules to make it permanent.
On Rev. 1 boards use GPIO 21 instead of 27.

Raspberry Pi to Arduino Shield Bridge
Connect your Arduino Shields with your Raspberry Pi or use our popular MI0283QT- Adapter (2,8“ Color LCD + Touch).
OnBoard you find an ATmega328 with preprogrammed Arduino bootloader.
