As far as I know Coreboot can not drive VGA and monitor by itself. There is not enough code to do that and nothing is displayed on monitor when you run Coreboot only.
It only sets up some parameters regarding to VGA which will be used by Linux kernel later.
This seems strange to me. Besides, I've got the Coreinfo payload working when trying out Coreboot in Qemu, so obviously there's some VGA code somewhere that works at least when the Coreinfo stage has been reached, but I still get nothing when flashing Coreboot onto my bios chip.
When you use FILO as a payload, your key-presses may be detected like ESC button though i did not test it myself but I found some keyboard manipulating code....

You'd better buy a debug card and plug into the PCI slot and see what numbers it will display. It has two seven segment components. Besides you can disable coreboot post codes and insert your own post codes to see how far the program runs. I did the same for my motherboard...
Thanks, but as I wrote on April 13th, I have managed to get some output over serial, but still nothing on VGA or any response to keyboard events. Details, and serial log and config file, can be found in my April 13th message.
