There a also some x86 mainboards which supported by coreboot. You could run your boot loader or kernel with initrd from the flash chip, if the capacity is big enough or you create your own embedded system with tor. And all works very well ...

If you want a stateless computer, currently a good option might be a laptop supported in Coreboot (*without the management engine blob etc*), write protecting the flash chip, and running Tails or Tor ramdisk from a CD. I own an old Lenovo X200 and it works well.
