What you need is an exaustive list of past versions plus
a catch-all for future versions:

	case "${kernel}" in
		1.*|2.0.*|2.1.*|2.2.*|2.3.*)
			echo "too old"
			;;
		2.4.*)
			echo "Linux-2.4 style"
			;;
		2.5.*)
			echo "unstable and not supported"
			;;
		*)
			echo "2.6 or newer"
			;;
	esac

We don't break ABIs as a rule, so you should always assume
that a newer version will keep working.
