The thing is that roms/seabios directory is _empty_ in
qemu-KVM-0.12.3.tar.gz.  So I can't use the sources you
(the qemu-kvm team anyway) ship because there's no shipped
sources, so I have to try to be clever and find a way to
deal with the issue.

But now when you mentioned it and I _finally_ found the
bios source in qemu-0.12.3, maybe I'll be even more
clever and will patch qemu-kvm with bits missing in it
from qemu-0.12.3.  Ugly but at least doable.

Maybe wider testing in debian and/or ubuntu is a good justification? :)

Thanks!
