I remember a thread on linux-kernel about the same issue a long time ago,
and the problem turned out to be init running sync() at regular intervals.
If I remember rightly, the author of init (Miquel V. Smoorenburg) wanted
to keep the sync() in there because it was "safer" in case of power
failure. The laptop community thought otherwise.
I was fairly sure the laptop guys won, and they fixed that, though. Maybe
they haven't (or Miquel snuck it back in :)
"apt-get source init" and see if you can locate the sync() and kill it :)
