Yes, I install Libreboot myself with a RaspberryPi and Pomona 5250 testing clip. Anything that’s already supported by Coreboot, can be supported to Libreboot. They have a list of hardware that they currently support listed here:
I actually sold Libreboot laptops previously on eBay, I used to sell the T440p a lot. Now, I’m about to setup my own website so I can start selling them for even cheaper. I also helped add Libreboot support for the Dell Optiplex 9020/7020 (Real thanks goto Mate Kukri, as I used his Optiplex port from Coreboot).
Position: Experimental 6DoF tracking support with external SLAM/VIO systems is upstreamed but still being worked on. Tested with RealSense D455 and Samsung Odyssey+, Reverb G2, Oculus Rift S.
Additional Notes: HMD only, no controllers. Tested: HP Reverb, HP Reverb G2, Samsung Odyssey, Lenovo Explorer, others: maybe.
