In src/Kconfig there is this:
config FALLBACK_VGA_BIOS_ID
string "VGA BIOS ID"
depends on VGA_BIOS
default "1106,3230"
help
The ID that would associate your VGA BIOS to your video card.
(PCI VendorID, PCI Device ID)
How does a component (nb, sb, sio) or mainboard provide an override
for this default?
