Well, there was no older seabios shipping with F16, so it made sense.
As for virt-preview, seabios updates were also available there long
before the qemu which required them.  Enabling virt-preview and doing a
yum update would have installed the new seabios as well.  I just don't
think that virt-preview can ever be trusted to pick and choose specific
packages, you either want the F15 virt stack as it is, or the F16
(virt-preview) virt stack.
