Thank you for taking the time to report this bug and helping to make Ubuntu better.
You might not have noticed, but laptop_mode is disabled by default in /etc/default/acpi-support. So if you remove acpi-support it will work. But changing this setting in /etc/default/acpi-support would be better:

# Switch to laptop-mode on battery power - off by default as it causes odd
# hangs on some machines. (Note: This is reported to cause breakage in
# Debian - see deb bug #425800. Leaving enabled for Ubuntu for now
# since presumably it's still valid here.)
ENABLE_LAPTOP_MODE=false

if you set this to true, laptop_mode will work. But remember that using laptop_mode can result in data loss since the hard drive is spun down and changes aren't saved.
