Most likely solution is to add missing modules to grub, like cryptodisk.mod
at least (thanks to the people at #coreboot. Hey, did the guys at Twitter get
the # thing from irc?).
I need to modify the Kcinfig file before rebuilding grub, and re-insert it in
the rom, which I need to reflash.
It might have cost me the whole day, but at least most of the install is
done. hopefully this is the last main hurdle.
I'd really like to configure Seabios to boot directly into grub, if possible.
There must be at least a boot order config.
