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.
That isn't going to work I think. sgabios works by hijaking vgabios, and when loaded as coreboot payload grub2 probably will not try to use vgabios in the first place ...
