By default, the Linux kernel will automatically disable ACPI on computers with bios which are older then 2000. However, many of the computers which have ACPI disabled, are in fact ACPI compliant.

I propose we create an online lookup database which ubuntu can check for hardware ACPI compliance, and offer to install ACPI support for computers which support it. A semi-automatic testing tool can be made which is also offered to users with pre-2000 computers, to submit to the database.

At the very least, a checkbox should be offered in the configuration panel, where ACPI can be easily forced and users can be shown their expected success rate. This will also eliminate the need for users to mess with grub.lst, potentially messing up booting entirely to give ACPI=force a try.
