The board booted fine, except I have no video, serial port or ability to write to the BIOS chip.
No video -> you need to include the extracted VGA bios from original BIOS. No serial port looks like wrong superio setup. No ability to write to the chip sounds interesting ? What do you mean by that. Flashrom cannot no-long overwrite the chip content? Maybe just some GPIO needs to be raised. Do you have more PLCC chips or other boards so you can hotswap them?
I do not think that there is anything board specific in the VGA code that i once wrote for this display hardware. Did my code break in the last two years?
For the VGA you need to use bios_extract and extract the VGA bios from orig bios image and tell coreboot via menu to include that (you need just pci ID lspci -n will tell)
Again, this board should have native code for bringing a basic vga textmode to life.
