If you have a built-in VGA device that requires an option rom from
flash, then you also need to set something like:

#define OPTIONROM_BDF_1 pci_to_bdf(0x01, 0x00, 0)
#define OPTIONROM_MEM_1 0xfffc0000

in src/config.h.  Adjust the BDA and memory location to correspond to
the rom location and the Bus/Dev/Fn for the vga card as reported by
lspci (eg, the above would correspond with "01:00.0" with the option
rom at the start of a 256KiB flash).
