It should be discovered automatically.

Indeed so.

Are you using Kconfig or the old method with buildtarget?

With Kconfig the way to do it is to select if and how to run the VGA
BIOS (which x86 emulator to use, or if to run in real mode) and
provide the filename.

Not all VGA BIOSes work when run by coreboot, so sometimes it's
neccessary to use SeaBIOS as payload and let it run the VGA BIOS.
