Are you sure this is actually a problem? Can you really exec these files, or is it just a matter of the flag? Some changes were made to mount flags by Al Viro. If you really want the flags gone, you should use a different umask (e.g. umask=111). The noexec flag means (for filesystems that actually have permissions) that _even if_ the "x" bit is set, it cannot be executed.
