super cool and detailed writeup ^^ I've been considering librebooting my Thinkpad X60, which I'm pretty sure is support by Libreboot and this will help alot :D

No, you can internally flash the X60. This guide will not apply to you in any amount. just read the docs! They're really good :)

there's one thing i'm curious about: is it any faster than the stock firmware?

POST, sleep/wake, and the EFI framebuffer all feel pitifully sluggish to me on the T480 (as compared with e.g. the X230), so if there's any motivation for me to flash mine, that would be it

@DenebTM i mean, i did not take any measurements, but POST is much faster, because its far less bloated than the stock BIOS. EFI support is not added yet, you gotta use BIOS boot (which is arguably better just because of its minimalism). S3 wake i don't know.

Had a similar reaction to the T480 being coreboot-able! It was like, they did what!?! I'm curious to see what bugs are present in the coreboot port and when they'll be fixed.

@ezntek great job! Would you or some of you guys @bneils @DenebTM be interested in a possible community effort of heads port to the T480?
