Everything seems to be working but I have a bunch of unclaimed devices. Does anyone know what these are and the kernel option to choose for them?

These are just control blocks on the processor itself, there are no drivers for them.

You'll be fine without a driver for them - they are CPU internal controllers, they will come up and autoprogram themselves on bootup and won't need any programming afterwards. A driver is only needed to debug your cpu or system hardware, and only Intel or system OEMs knows how to program them (at least for the most part.)
