Did you look at the attachment? None of it is in any way macppc  
specific. All it does is to pass a name, an i2c_tag_t and a bus  
address. Nothing MD in there. ( the node member isn't in use anyway  
and should have been deleted long ago )

Again, that's nonsense. You can recycle the exact same attachment on  
either one of them.

I have no idea how you got to that conclusion.
