Interesting, can you tell more about this project? Did you also modify
QEMU to emulate the HW setup?

We should try to isolate the dependencies for QEMU, even if QEMU is
probably the most interesting use case for OpenBIOS these days. Could
you tell more about those bugs and even better, publish your changes?
