There is an open source VGA Option ROM coming as part of the SeaBIOS
repository (http://www.seabios.org/). However, it only has support for
the Qemu graphics hardware (and some AMD Geode iirc). So in order to get
it working on your particular graphics card you will have to write code
that initializes the card (that might include initializing the RAM and
GPU on the card, etc). You can run your graphics card option rom in
x86emu and turn logging on to see what hardware accesses it does and try
to replay some of it. It will still need a lot of work to get this
running. Good luck!
