I'd suggest to just have grub2 drive the serial line directly, IIRC the magic words are "terminal_input serial; terminal_output serial".
I know this solution but I prefere sgabios myself as it allow me to chainload non serial compatible elements. My board doesn't have vga port, only serial so sgabios is perfect for me.
I tried building coreboot with VGA_ROM_RUN=y and ./cbfstool coreboot.rom add -f …/sgabios.bin -n vgaroms/sgabios.bin -t raw but it doesn't work. -- Regards Maxime
