What about pre-ME thinkpads, after replacing the wifi card with an ath9k/open source firmware one? Does the intel chipset graphic require a blob for simple framebuffer/textmode operation? Because I can't remember including any blobs in the libreboot I use there, and iirc I get output before a linux kernel is able to load device firmware. It is 64bit, and runs pretty much anything from (from what I can tell, but not sure, due to CHMPXCHG16B) Windows 10, over FreeBSD to Android. Probably even something like QNX. Yes, you might not call this reasonably modern, but according to the hard facts you listed as qualifiers for being reasonably modern, they tick off.

Pretty sure that has a BIOS

Unless it is running the "coreboot BIOS" (which very few things are), then it has a binary "non-free" blob booting it up.

  I don't remember whether the video BIOS was extracted from the old binary or if it is the open-source replacement, but I'd tend towards the latter as I don't remember searching for the backup/dump of the original firmware. And yes, it's running coreboot, and at least CLI/linux-framebuffer arch linux works. I didn't yet get to setting the rest of the system up, but considering I bought it specifically for high-security operation, as the ME can be physically removed without loosing more than the build-in Ethernet port, I'm not pressed to do it anytime soon. Edit: I'm pretty sure I followed [0], which leads me to the new conclusion that I did use libreboot, a more strict version of coreboot (think coreboot=Archlinux, libreboot=GNU Guix), and had to fiddle with the question whether the open-source video bios would work. This confuses me a little, as I remembered buying an X61s, not an X60s, but from the fact that it booted after flashing, I deduce it had to be an X60.
