Please answer following:

1) do you port new motherboard ?

2) if you  set speed to 115200 do you see something if you set on the other side 
57600 or 28200 bauds?

3) if you set coreboot to 57600 and the other side to 115200 do you get something?

4) Sometimes when the clock is nearly 115200 but a bit off some USB serials 
cannot handle that. Maybe you can try to connect some other device, or try to 
test with some real serial line on some other PC.
