Well without procfs, you are stuck with groveling through kmem. Kmem is a terrible interface for this type of thing, as it requires a recompile of many utilites when the kernel structures change. It is arguable much more dangerous as well, since it requires access to all of kernel memory. Procfs (and the like) provide a much cleaner interface, and will probably stick around for a good long time. If anything, the use of kmem for this type of thing should go away altogether.
