ERk.
  So if I needed to read values from four i2c devices (raw access would be
fine) and I need to get this working in a few days, how would you suggest I
proceed?  Kernel = 2.6.23+.

  Do I need to start from scratch?

  Start by using Jon's patch  (or are the 5200 i2c and the cpm2 i2c
completely incompatible?)

  What about other cpm2/i2c threads - Did they ever complete?
