The ACPI info comes from the BIOS. So, it's no more reliable than any
other BIOS, and probably less so than ones that do/did DMI, as there are
so many aspects to it.

I would suggest reading the ACPI spec at http://acpi.info and the Intel
implementation of it at

http://developer.intel.com/technology/IAPC/acpi/index.htm

for an idea of what it's supposed to do and what you can theoretically get
from it.
