A vbe rom isn't a big deal.  You probably want support the 0x01CE and
0x01CF ports (on x86) so the vgabios running in real mode can easily
reach the bochs interface registers without a protected mode round trip
for mmio access.

I *think* for seavgabios this needs just a rebuild with an approximate
configuration (see roms/Makefile and roms/config.vga.*).  The code
already checks whenever bar 0 is actually memory not mmio because this
is needed for the vmware vga too.

HTH,
