Yes I have tried chainloading, but I can't chainload a BSD partition
from libreboot Grub. What I do is chainload SeaBIOS and from there I
have Grub in a partition, with that Grub I can indeed chainload the
BSDs. But the problem lies in that BSD* (or Hurd I suspect) won't boot
into framebuffer for now, while Linux does.
SeaBIOSVGA doesn't initialize properly the GM45 card of the X200. For
that I need a BIOS backup of an X200 in order to extract this propietary
blob, and include it as option rom. I have also downloaded BIOS updates,
but I haven't been able to extract this blob. And I will be able to get
rid of it when OpenBSD boots into framebuffer.

Some BSD make BIOS calls and may not work with Coreboot.

We have tested some of the BSD OSes and have seen, that FreeBSD for
example
makes BIOS calls, which is not supported by coreboot. Possibly with
help of
SeaBIOS, it may be possible to boot FreeBSD like it is now, but the
right
thing to do, is to remove FreeBSD's dependence on BIOS calls.
...
Please feel free to test booting any of the above using SeaBIOS and
report to
the coreboot mailing list.

Have you tried a Grub2 chainload, with Grub2 as the payload for
libreboot?

Best of luck.
