Actually, I think the generic solution has been to not use option roms at
all. :-) After all, most cards don't use them (VGA being the notable
exception).
Frankly, if I had any pull with manufactures or vendors, I'd try to
convince them to avoid option roms instead of trying to convince them to
support a different option rom format.
Having cards that conform to standards (or can emulate them during bootup)
will be a lot more productive IMO, then a cross platform byte code.
