You can run binaries regardless of both noexec and the execute
permission bits, too.  It's not clear that there's any point to the
option at all.

    rjk@rollercoaster$ ls -l /boot/ls.noexec 
    -rw-r--r--    1 root     rjk         43784 Feb  3 13:40 /boot/ls.noexec
    rjk@rollercoaster$ mount | grep /boot
    /dev/hda1 on /boot type ext3 (rw,noexec,errors=remount-ro)

    rjk@rollercoaster$ /lib/ld-linux.so.2 /boot/ls.noexec
