I want to buy a Libreboot X200 notebook, however, I also want to use it
with FreeBSD. I'm not sure if that works, so I asked Gluglug directly
and got the following response:

Can some FreeBSD developers make a statement on this topic? If it
doesn't work, then I can test some patches, if someone writes them, but
I'm a sysadmin, not a programmer, so I'm not really able to write some code.
