CompuLab 686CORE (CM-i686) general purpose input output regi

Hello,

Has any one done work on GPIOs of the CM-i686 (previously known as
686CORE) ? Specifically, these are the GPIOs on the Winbond Super I/O
chip W83627HF/F (and not the I/Os of the Geode).

Documentation from CompuLab is not very detailed, and all I have is the
attached sample code.

Any help would be much appreciated!

Alain.
