The driver says this at its head:-
/*
i2c bus driver for ACCESS.bus (ACB).
Copyright (c) 2000 National Semiconductor Corporation
Author : James.Mundenmaney at nsc.com
*/
/* This implements an i2c algorithm/adapter for NSC ACCESS.bus
interfaces of National Semiconductor Corporation's Geode
family IA on a chip. The SuperIO module of the Geode family
IA on a chip has two ACCESS.bus interfaces (ACB). This module
implements the ACB algorithm and adapter specific modules. */
I can send the file to you (or you can download it along with all the
rest of the linux drivers) from the routerboard.com web site.
