No. But on sparc64 the iic(4) bus attachment can be argumented by the
OFW device tree. I have code to do this. It needs a more general
solution as other architectures have similar problems. There was a
discussion on tech-kern. My solution (inspired by iic(4) from OpenBSD)
needs every existing iic(4) driver to be modified and was rejected
because of this. An alternative solution would be to write a sparc64 MD
alipm(4) and iic(4). See macppc for an example of this approach.
