For 2.5 I have some plans to make obsolete syscalls depend on CONFIG_COMPAT_*, this allows to compile big and bloated kernel for compatiblity and smaller kernels without that (e.g. for embedded devices). And in fact we have quite a loft of cruft that can go away for setups only having very modern userspace..
