How does HAL actually do the suspend? If it just calls the
/usr/share/hal/scripts/hal-system-power-(suspend|shutdown|hibernate)
scripts you have nothing special to do. This script already checks for
the powersave binary and if its is found it uses powersave for handling
the actual suspend.
Three points that you should consider for kubuntu:
1.) DBus access is controlled via the group plugdev in Debian. As Ubuntu
now has libpam_foreground you could simply delete the
debian/patches/dbus_access.diff patch of the powersave source package.
2.) The shell scripts of the acpi-support package should check for a
running powersaved process and if found simply exit and leave the acpi
event processing to powersaved. Take the sleep.sh script for example. It
should contain something like this
if pidof powersaved ; then
exit 0
fi
at the beginning of the script.
3.) Make sure that no other cpufrequency scaling daemon is installed as
powersaved handles this itself.
If you have more questions, please ask.

Michael
