I'm not sure what you mean.  The difficulty is going to be in passing
the information from the coreboot option rom scan to seabios so that
seabios can properly boot the machine (and fail over to an alternative
boot source if necessary).  I suppose one could add the legacy bios
bootup rules to coreboot, but I don't like that idea much.
