Unfortunately, Finnix doesn't try to access I2C bus, not even to initialize

The kernel in Finnix seems to have a driver but unfortunately I2C
debugging is not enabled so you probably won't get much useful info. The
best idea in this case is probably to compile a kernel with debugging
messages for I2C so you get some info on where it fails if it tries to
find the bus at all.
It could be that the problem is that the device tree does not correctly
describe something. Real hardware seems to have two i2c aliases related to
some serial ports that is believed to maybe causing problems with MacOS 9
(see:

ki2c-serial: /address@hidden/@d/address@hidden/i2c/cereal
and
ui2c-serial: /uni-n/i2c/cereal
but I don't know if any of this is relevant, just mentioning it in the
hope that some of this might help. (I've also noticed that real
PowerMac3,1 seems to have a modem connected to one of its serial ports so
that could also be something MacOS 9 is looking for or tries to use.)
