[Soekris] Error LED on 4801

[ajv]

The net4801 contains a SC1100 processor and a PC87366 I/O controller.
Both chips have GPIO pins. I think the GPIO pins of the PC87366 are used.
To see how it is wired I would like to have the schematic diagram of the 
4801 printed
circuit board, but was unable to find it on the Soekris site.

Is this diagram available?
