Ubuntu does not require ACPI to be present in order to work. If the kernel attempts to load an ACPI module, but finds that the computer does not support it, or is too old for it to work reliably, it will display a small banner across the top of the screen for a second, and continue booting.
To turn off the attempt to load ACPI, press F6 on the boot menu for the CD, and add
acpi=off
You may have to modify the GRUB menu after installation to make the change permanent. To modify the GRUB menu, open a terminal, and enter
sudo gedit /boot/grub/menu.lst
The add the "acpi=off" to the kernel line of each entry.
