I've observed this issue with acpid/acpi-support, gnome-power-manager and xfce4-power-manager in Ubuntu 11.04 and Xubuntu 11.04 and 11.10, so I'm thinking that it might be an xorg issue.

After running 'xset dpms force off' with lid closed on a laptop to disable the backlight, moving the mouse or touching the keyboard will cause the backlight to turn back on. The backlight should never turn on under any circumstances when the lid is closed, unless maybe in the case that the user runs 'xset dpms force on' explicitly.
