The only case I can think of is PCI, where we ignored the ACPI-provided resources until fairly recently. That was a somewhat reasonable thing to do, since the hardware still had to support pre-ACPI operating systems and so the non-ACPI information sources were typically correct.
Other than that, I think we always trust the ACPI data.
