So after the ./install.sh and installation of the cape and then power up I 
do now have access to my DS1822 via a Python app.  But another vanishing 
act, possibly due to the change from the SLOTs approach, is the hex dump 
below isn't possible anymore.

debian@ebb:~$ cat /sys/bus/i2c/devices/1-0057/eeprom | hexdump -C
cat: /sys/bus/i2c/devices/1-0057/eeprom: No such file or directory

So where did the i2c eeprom go?  Does the /boot/uEnv.txt need to have i2c 
explicitly set to access the cape eeproms?

debian@ebb:/sys/devices$ ls
armv7_cortex_a8  platform  software  tracepoint  w1_bus_master1
breakpoint       soc0      system    virtual
