Nope, not as it is. Useful != supportable.
1. It must not create any files under /proc/acpi
This is creating a machine-specific API, which
is exactly what we don't want Nobody can maintain
50 machine specific APIs.
These objects must appear generic and under sysfs
as if acpi were not involved in providing them.
2. its source code shall not live in drivers/acpi
it is not part of the ACPI implementation after all --
it is a platform specific driver.
