I dropped in to the open evening last Wednesday to ask for help in flashing my Lenovo X200 with libreboot. The process is described here, in completeness, with a BeagleBone Black:

There's a bit of info on why we should do this on libreboot.org and of course Richard Stallman's website.

Thanks in advance for any help! All best, Richard
