Agreed.

I extracted and disassembled the acpidump.  There were five
occurrences of PNP0C02:

DSDT.dsl  \_SB.PCI0.LPCB.LDRC (has a constant _CRS)
DSDT.dsl  \_SB.PCI0.LPCB.CWDT (has _HID INT3F0D and _CID PNP0C02, so
doesn't match message)
DSDT.dsl  \_SB.PCI0.PDRC
SSDT1.dsl  \_SB.PTID (has no _CRS and has _HID INT340E and _CID
PNP0C02, so doesn't match message)
SSDT4.dsl  \_SB.IFFS (has no _CRS)

So I think PDRC must be the one causing the trouble.  Its _CRS runs
some AML, but I'm not AML-savvy enough to figure it out:

    Scope (_SB.PCI0)
    {
        Device (PDRC)
        {
            Name (_HID, EisaId ("PNP0C02"))
            Name (_UID, One)
            Name (BUF0, ResourceTemplate ()
            {
