Perhaps using a config option wasn't the right way to do this - a kernel boot parameter might be better. In fact, one could envisage a kernel boot parameter "sysfs_version=N" which will allow distro people to select the sysfs-of-the-day which works with their userspace. Because it does appear that we need _something_ which will get us away from this ongoing problem of needing to keep the kernel and userspace synchronised across sysfs changes.
