Yes, I did mean annoying (auto correction...). I must apologize for this
statement. My intention was to provoke a reaction (and this seems to
have worked just fine) but perhaps I was a bit too unkind...

I don't know which bug you mean , but I think the harddisk load/unload
cycle thing is a totally different issue. The package laptop-mode-tools
offers a lot more functionality than just setting the (potentially
dangerous) hdparm -S option.

I think that all packages (and especially those that are likely to be
used together) should support each other as well as possible. The
present setup just does not work properly without edition conf files,
which i regard as acceptable for the testing branch but unaccepatble for
a stable release.
The problem is, that laptop-mode-tools sets some options (especially
hdparm options for acoustic management, spin down, ...) that are not
persistent. Therefor it needs to be noticed when the computer resumes
from suspend/hibernate. As mentioned by Bart Samwel acpi-support does
just that and it works fine.
To exactly mimic the behavior of acpi-support one would have to add
something like
#!/bin/sh
#
# 99laptop-mode: Reload laptop mode
case "$1" in
hibernate|suspend)
if [ -e /etc/init.d/laptop-mode ] ; then
invoke-rc.d laptop-mode stop
fi
;;
thaw|resume)
if [ -e /etc/init.d/laptop-mode ] ; then
invoke-rc.d laptop-mode restart
fi
;;
*) exit $NA
;;
esac
to /usr/lib/pm-utils/sleep.d . I personally have my machine set up like
this and everything works flawless.

If laptop-mode-tools is not installed this hook would do nothing at all.

I dont think this is necessary.

I don't think that they will come in each others way (at least they do
not on my computer), but perhaps Bart can comment on this.

For a user this doesn't matter, but either of you should add it, as the
laptop-mode-tools package is rather useless if it fails after each suspend.
