It sounds to me as though the PCI id's of the graphics card for the
upgraded CPU may be different (I could be totally wrong about that, so I
defer to others on the list if I'm barking up the wrong tree) and your
coreboot image may need to be updated accordingly. Of course, it could
also be the video BIOS that's the problem as you've suggested.

I upgraded the CPU in my F2A-85M from a A4-5300 (Trinity) to a A10-6700 (Richland). The
board had Coreboot installed before with the VGA BIOS extracted from the A4-5300. However,
I did not get any video output when trying to boot after the upgrade, so I replaced the
flash chip with a backup with the vendor BIOS that works.
Is it likely that the A10-6700 needs a different VGA BIOS or does this this rather look
like a different issue? I don't want to experiment too much because the BIOS chips are
hardware-wise pretty fragile (even when using the extractor tool).
