[coreboot] Asrock IMB-A180 not booting

[Prop 395]

I tried the .config file and adjusted the VBIOS for my dev system, but I 
am still getting the same results (no video).  The sticker on the 
motherboard near the power connector says IMB-A180E-H E. Printed on the 
right edge of the motherboard near the heat sink it says IMB-A180-H REV. 
G/A 1.02.

I also tried the stock AMI BIOS to confirm it still works (and it did).

Do I just have a bad board?
