My guess is you have all sorts of funny daemons running that peek at the
disk every few seconds. With LinuxPPC I had to disable things like
icecast, crossfire, and I think even sendmail, before disk activity would
drop to a sane level.
Another candidate is the drive_applet in the gnome panel.
lsof +D /var should show some of the usual suspects. If you can convince
syslogd to write to the log less often this might help, too. I didn't
tweak any bdflush parameters (tried that before disabling the crazy
services and it didn't help). And I don't get the disk to spin down all of
the time...
Hope this helps a bit,
Michael
