You don't really have a choice.  You could be doing hardware passthrough 
and the ROM on the card may hijack int19.

I don't disagree.

I think the best thing to do is to let SeaBIOS create a boot order table 
that contains descriptive information and then advertise that to QEMU.

QEMU can then try to associate the list of bootable devices with it's 
own set of devices and select a preferred order that it can then give 
back to SeaBIOS.  SeaBIOS can then present that list to the user for 
additional refinement.
