Based on bootc.net's Wheezy image, these are the modules needed for DS1307 RTC and TMP102 temp sensor:

tmp102 hwmon rtc_ds1307

Thanks! I saw:

Is there somewhere to download new compiled kernel for Occidentalis?

Please be patient, we are still working! Releases will be announced on the Adafruit Blog for those who do not want to compile their own kernels :)

Y'all really do take Friday Piday seriously :) I just saw Occidentalist v0.2 and the RTC tutorial. I look forward to trying it out tonight. Interesting to see how you left off the one resistor to make it safe without level shifter. Thanks!
