OK, I find the discussion, thanks for pointing that out. that out. Related
question: the ICH3-M spec specifies the PM2_CNT address at PMBASE + 0x20,
just before the GPE block. This seems consistent with my FADT, which places
PMBASE at 0xe400 and GPE0_BLK at 0xe428. Would manual poking at the
presumed location of ARB_DIS or FADT override work?
Best regards,
