In the ACPI case it's the same code registering the thermal zone and 
creating the thermal devices, whereas in this case there's two separate 
drivers involved. You need some way to get from an i2c device to a 
thermal device.

There's nothing in this solution that's limited to GPUs. The generic 
thermal code is already used by ACPI.
