I want to test the new acpi_thermal and I'm using something like that BEOS_ADD_ONS_DRIVERS_ACPI = $(X86_ONLY)acpi_button $(X86_ONLY)acpi_thermal ; in HaikuImage file, but at boot I get error messages like Search for drivers/power/acpi_thermal/driver_v1 failed and something about the api_version not setted. Is this procedure correct? Regards, Francesco Piccinno
