SeaBIOS calls option roms in big real mode.  This is required by the
relevant specs.

See the transition16big function in src/romlayout.S.  It briefly jumps
to an address at 0xffxxx during the transition to real-mode.  At a
quick glance, it looks like it could probably be changed to not use a
code address >64K.
