unlike legacy firmware (e.g. BIOS, UEFI) coreboot doesn't have persis- tent drivers in the background that GRUB could call back to ask to switch a video mode. So you have to configure coreboot to already start in a video mode. What you are looking for is CONFIG_GENERIC_LINEAR_FRAMEBUFFER as opposed to the CONFIG_VGA_TEXT_FRAMEBUFFER=y that you have currently selected. I'm not sure if you have to configure anything in GRUB too, to get the background image to work. I would guess that it just works, though.
