Try a 'cbmem -t' to see how long coreboot itself took to boot. There might be some delay somewhere causing it to take longer to boot (current system I'm on, it takes 8 seconds, and on other systems I saw it take 15 seconds, because it waits for the ME to respond until it times out) so it might not all be seabios' fault. Also I just tried removing the VGABIOS and setting Coreboot to run the GOP driver, and I got a black screen in seabios (even in grub, screen shows text only after linux boots and inits the driver I think). I'd suggest you try the proper vgabios and no GOP driver, just to see if it helps, then see what happens without the vgabios. Note: i only have one VGA device here.
