Bought a 2.5mm to 3.5mm converter cable (sku.7127 at dealextreme).
It has the following pin-layout: TRRS: left, right, mic (unconnected), ground
Unfortunately this is incompatible with the FR which uses TRRS: mic, right, left, ground
Currently running a 2.6.34-oe4+gitr3 kernel from shr-kms with debian (squeeze/sid) as OS.
The touchscreen was misconfigured (could not reach all the corners with the cursor, and also the axes were messed up) in X. Calibration failed as there's no longer a /sys/.../calibrate. Also the option in the InputDevice section where ignored as udev (157) was already providing the input device. So I fixed it by removing the unused inputdevice section and adding:
Section "InputClass" Identifier "S3C24XX TouchScreen" MatchDevicePath "/dev/input/event1" Option "GrabDevice" "1" Option "InvertY" "1" Option "Calibration" "110 920 110 920" Option "SwapAxes" "1" EndSection
note: /etc/pointercal doesn't seem to be used anymore
