Provided, actually, it seems they are moving away from it.
There are other examples, including acpi_power_meter and many drivers
under drivers/platform/x86 which do expose some hardware monitoring
features based on proprietary BIOS interfaces, sometimes using ACPI,
That being said, I can't disagree with Ian: in most cases, when you see
the warning message, there is no APCI driver you can use, and this is a
real problem looking for a solution. The ball is in the vendor's court
