I just checked Linux source. arch/powerpc/platforms/powermac/low_i2c.c is searching for 3 types of I2C buses
- if some device in DT is compatible with "keywest-i2c"
- if CONFIG_ADB_PMU is set, if some device in DT is named "pmu-i2c" or "via-pmu"
- if CONFIG_PMAC_SMU is set, if some device in DT is named "smu-i2c-control" or "smu"
So, OpenBIOS needs to be changed to declare an I2C bus.
Then, maybe, I'll get some bus probing.

Hervé
