UPDATE: xserver-xorg-input-tslib is in Debian official now!
You may download the xserver-xorg-input-tslib deb here.
You may get xserver-xorg-input-tslib's upstream source here.
(Get those named xf86-input-tslib*.)
1. It is hard coded to use only /dev/event0 now. You may link /dev/input/event1 or the device you are using to it.
2. It works fine with default resolution 480x640. I have not solve the screen rotation issue yet.
3. My working /etc/X11/xorg.conf section:
Identifier "Configured Mouse"
Option "Device" "/dev/input/event1"
Option "Protocol" "Auto"
