at all for i2c clients.

That actually simplifies things for us, thanks for checking.

Unfortunately, while that may be true for old stuff, most recent
powermacs do. Encoding is mostly like sparc though (see other mails).

Thanks for the clarification.  The bus encoding seems different

I've started a dialogue between Scott and the openfirmware Sun
folks I know so that hopefully Scott can get a copy of the I2C
bindings Sun uses and we can sort all of this out.
