about it.

* EEPROM ADDRESS SELECTION. Initialize the I2C interface, which
* is used to access the onboard serial EEPROM. The EEPROM's I2C
* DeviceAddress is hardwired to a value that is dependent on the
* 626 board revision. On all board revisions, the EEPROM stores
* TrimDAC calibration constants for analog I/O. On RevB and
* higher boards, the DeviceAddress is hardwired to 0 to enable
* the EEPROM to also store the PCI SubVendorID and SubDeviceID;
* this is the address at which the SAA7146 expects a
* configuration EEPROM to reside. On RevA boards, the EEPROM
* device address, which is hardwired to 4, prevents the SAA7146
* from retrieving PCI sub-IDs, so the SAA7146 uses its built-in
* default values, instead.
