I also think this bug is definitely with pm-utils, if pm-utils is meant to replace l-m-t. Using 10.04.1 LTS and NOT having l-m-t installed, I cannot suspend with the lid on AC power. If I install l-m-t and choose enable acpi-support and configure laptopmodetools.conf to use acpi on ac and with lid closed on AC everything works as per Karmic.
