Not really.

drivers/built-in.o: In function `acpi_video_bus_put_one_device':
/root/kernel/linux/drivers/acpi/video.c:1407: undefined reference to `thermal_cooling_device_unregister'
drivers/built-in.o: In function `acpi_video_device_find_cap':
/root/kernel/linux/drivers/acpi/video.c:842: undefined reference to `thermal_cooling_device_register'
make: *** [vmlinux] Error 1

It is CONFIG_THERMAL=m this time.
