No I2C is as old as the hills, I2C is a philips serial

radios.

well, there are other versions faster and with bigger address ranges... but
that wasn't my point.

we are all quite familiar with i2c.

the new thing here is the particular Apple hardware, registers etc. used to
implement the bus interface... another set of stuff we may have to deduce
the hard way.

it's not the cuda - the iBook doesn't have a cuda - AFAIK.  (PMU, I expect).

and... actually, I think the asics are more there to keep costs down... but
each to his own ;-)
