Yes, my mistake :)

That's a good point. For us, however, the only alternative is to depend
on other packages to provide these blobs (bochsbios, vgabios,

Ok. I'll change our bochsbios build to build a specific QEMU bios with
these changes. That should make everyone happy.
I sense that any response to this e-mail would be off topic for the ml
