Never the less I have a quick look and add some printk():
...
unsigned long cpqfcTS_ReadNVRAM( void* GPIOin, void* GPIOout , USHORT count,
	UCHAR *buf )
{
  unsigned short i;

  if( !( tl_i2c_tx_start(GPIOin, GPIOout) ))
    return FALSE;

    printk(">>> %s step1\n", __FUNCTION__);

  // Select the NVRAM for "dummy" write, to set the address
    printk(">>> GPIOout %p\n", GPIOout);
    printk(">>> SLAVE_WRITE_ADDRESS: %d\n", SLAVE_WRITE_ADDRESS);

  tl_i2c_tx_byte( GPIOout , SLAVE_WRITE_ADDRESS );
  if ( !tl_i2c_rx_ack(GPIOin, GPIOout ) )
    return( FALSE );

    printk("%s step2\n", __FUNCTION__);
...

and notice that the ReadNVRAM failed earlier (dmesg):

So it seems that   tl_i2c_tx_byte() failled?

Is GPIout are OK?

I have not any detailed doc about this card, so any advise is well come.

Thanks again,
    Joel
