noatime means: don't write back access times.  usually when you
access a file (open...), the atime field of the file's inode is
updated to show the last access time.  this means you get things
to write back for any file that is opened.  disabling that helps
in getting spindown.

So, simply pass noatime to all your hard disk partitions.
