3.1 or 3.3 or 3.4 maybe? With a new enough kernel (3.4 I think), you can try the hw i2c controllers rather than the bit-banging bus; just load radeon with the parameter hw_i2c=1. > > BTW here is my lsmod: > Module Size Used by <snip> > As you can see, the i2c_powermac module doesn't seem to be used.
