The ACPI controller should appear as a PCI device, if it exists. You
should see a device listing from lspci for it. For instance on my desktop
(even though ACPI is not enabled) I see this:

00:07.3 Bridge: Intel Corp. 82371AB/EB/MB PIIX4 ACPI (rev 02)

Also there may be some settings related to it in the BIOS, although a lack
thereof does not mean that it doesn't support ACPI. I'd also be skeptical
of a 5-year old machine supporting ACPI, although it actually has been
around for a while, if not supported decently under Linux -- I know that
some Pentium-era hardware I have used supported it.

I have several laptops which all use ACPI, and none of them have the ACPI
controller as a PCI device. They are mainly SIS chip boxes, but I know
ACPI works on them (in fact some of them have no APM) as the support is
loaded and used to shutdown the machine.

Thanks for the suggestion, but it hasn't solved the problem. The kernel
reported that there were invalid ACPI PCI IRQ routing tables and other
messages indicated that ACPI wasn't present.

I guess I'll have to keep trying or just buy a new notebook.
