This could all be done with an of_platform driver instead, and avoid

I know i know. But it was decided, while both ppc/ and powerpc/ wander

The idea is to avoid regressions in arch/ppc; maintaining feature parity
isn't necessary. If, as you say above, 8xx i2c was already broken in
2.6 (even in arch/ppc), then I see no reason not to go to an of_device
It is apparent why - so far only mpc885 is alive in arch/powerpc, and it
is not going to change soon for 8xx.
Actually, I plan to do some arch/powerpc 8xx work over the next couple
