Update for the evening....
Thanks to great further work by Chris Boot (who I believe is on this list)
there is now an i2c driver using the i2c hardware on the RaspberryPi rather
than bitbanging the GPIO pin.
Again, all three i2c 1-wire masters are found.
Results for a DS18B20 connected to DS2483 bus master are as follows
root@berry:/boot# time /opt/owfs/bin/owread /uncached/bus.0/28.5B8A57030000/type
DS18B20
