This property is no longer necessary as - Nowadays, we have sysfs and the PCI devices in there do have a full Open Firmware device path exposed as a "devspec" file in their sysfs directories - I don't think anybody ever used that property in userland :) This mail is mostly to make sure of the later. I intend to get rid of it in 2.6.18 (that's early, but as I said, I think nobody uses it anyway. I intended to use it in some X stuff I never ended up actually implementing...) It only concerns 32 bits ppc machines with OF, and only the ones that renumber busses, which means basically only PowerMacs. Ben.
