Now I thing that my device tree is not completely working and thats why
linux got some collusion at the beginning ?? And I have no idea why graphic mode doesn't work since it looks like it finds vga without any problem.
Scan for VGA option rom Got ps2 nak (status=51); continuing ps2_recvbyte timeout
I can't see your VGA ROM getting run anywhere. Did I just miss it?
You could try having Coreboot run it with vm86 and with CONFIG_CONSOLE_VGA set to see if that works. I'm wondering why SeaBIOS isn't finding it.
