That sounds like a good idea.  Latest SeaBIOS git will launch any
option rom in the CBFS directory "genroms/".  For example, one can add
"genroms/sgabios.rom" or the lzma compressed
"genroms/sgabios.rom.lzma".  The rom(s) will be run after the vga and
PCI roms are run.

Adding ordering support is a bit of a pain.  Lets see if it is needed.
