It sounds like the sensor drivers want to talk to hardware that ACPI methods might also use. But I missed the details, such as the specific devices in question, which ports they use, how they are described in ACPI, which AML methods use those ports, and which non-ACPI drivers also use them. It also sounds like the non-ACPI drivers provide much more functionality than ACPI exposes. I'd like to understand this, too, because an obvious way to solve the problem would be to drop the non-ACPI drivers. Is this extra functionality available on Windows? If so, do we know whether Windows uses non-ACPI drivers or whether they have some smarter way to use ACPI? In the long run, I think the easiest, most reliable route would be to use the system in a similar way. Then we'd be doing things the way the manufacturer intended and we'd take advantage of all the Windows- focused firmware testing.
