Maybe we could switch PCIDevice to default romfile to try to
<devicename>.rom if none is specified. Since qdev names are unique, this
should work well.

Been there, tried that. It isn't *that* easy. The PCI ID in the option rom header doesn't match the PCI ID of the emulated lsi, so seabios refuses to load it from the rom bar.

Heh, I was wondering why it didn't work unless I put rombar=0 :-)

Is this fixable in a reasonable way or does PCI ID in the option rom represent a much newer device that would trigger issues with guest drivers?
