How different is the protocol to the DS1307?  I have my DS1307 talking
to NetBSD by creating a config file RPI_RTC:


include "arch/evbarm/conf/RPI"

no options      MODULAR
no options      MODULAR_DEFAULT_AUTOLOAD

dsrtc* at iic1 addr 0x68

options         USBVERBOSE      # verbose USB device autoconfig messages
