Here is Qubes on a Lenovo T400 with Coreboot:
  https://groups.google.com/d/msg/qubes-users/D9slVaqF1u4/84fFLfuYEwAJ

Some additional notes:
* Everything I wrote there, also holds for the T500 as well.
* Unfortunately, Libreboot still doesn't have the Coreboot IOMMU change yet.
* if you build Coreboot without microcode, there may be crashes during high CPU 
or Windows HVM usage. So you may need to add microcode (by adding ucode=scan to 
Xen command line).

If you are searching for a laptop and care about firmware blobs, here are some 
example systems:

Coreboot with no blobs, no management engine:
* Lenovo X200/T400/T500 w/ Coreboot, CPU performance-per-core about 50-60% of 
Skylake i7-7920HQ. Max 2 cores. Max 8 GB RAM.

Coreboot with partially removed management engine, open source RAM init, some 
minor blobs:
* Lenovo T530 w/ Coreboot, high-end configurations have CPU 
performance-per-core about 70-80% of Skylake i7-7920HQ. Max 4 cores. Max 16GB 
RAM.
* Lenovo W530 w/ Coreboot. Not officially supported, but someone made it work. 
Max 32 GB RAM.

Coreboot with partially removed management engine, proprietary RAM init
* later versions of Purism Librem
