I don't know how old your machine is:-)
Most of mine, according to acpi, are "too old" so ACPI disables itself.
I override it in grub's configuration. This is Sarge, not ubuntu:
title Debian GNU/Linux, kernel 2.6.7-1-686
kernel /vmlinuz-2.6.7-1-686 root=/dev/sda2 ro vga=791 acpi=force
The kernel parameters are set on this line:
# kopt=root=/dev/sda2 ro vga=791 acpi=force
and propogated by update-grub. Read the comments in /boot/grub/menu.lst
for more detail.
Note that other vendors do the same sort of thing a different way.

The messages in your next message show ACPI is not turned off.
This would've been better though:
dmesg | grep -i acpi
