If you guys created this format in your compressed openfirmware
trees, is it possible for you to "fix" it to match what Sparc
systems following the proper bindings do?

Possibly, though it'll cause some pain when old trees are used with a 
kernel that expects the new binding.

You mentioned having an actual binding document for I2C on Open 
Firmware; is it available online anywhere?

It's a Sun internal document I got from a Sun employee, I'll ask
if there is a way I can at least share it with you privately so
you can use it as a reference.

Don't PowerMACs and such have I2C controllers and devices?
How do they encode these I2C client device reg properties?

As far as I can tell from poking around 
http://penguinppc.org/historical/dev-trees-html/, they don't include reg 
at all for i2c clients.

That actually simplifies things for us, thanks for checking.
