Yes. I have an x86 platform which has an lm63 temperature sensor
connected to the i801. There are a couple of loose ends that I need to
take care of before I can send the DTS. I can send it for reference, but
it won't be of much use because other things are still missing from the
kernel and I don't know in what timeframe they can be applied.
