Build time dependencies aren't going to help anything, arm64 (and to my understanding some future x86 systems, LynxPoint IIRC) supports both DT and ACPI and so you have kernels built with support for both.
well, that's what I suggested initially: if (is_of_node(card->dev->fwnode))
I used the of_node test as a proxy for 'no DMI' since I am not aware of any means to detect if DMI is enabled at run-time.
