I can take this patch in the SCSI tree, but... do we really need two
models, considering that the PCI id is the same and that (for the
coolness factor of installing NT 3.1 onto an empty VM) we can just add
ESP support to SeaBIOS?  Does the option ROM not work without the EEPROM?

(Regarding ESP support in SeaBIOS, I have an almost working patch;
however, Windows XP setup fails at "Starting Windows" and I don't have
any older images nor time to investigate... I attach both the QEMU and
SeaBIOS changes, feel free to pick them up).
