Image of console exhibiting issue.

I was installing a VM last night under QEMU/KVM with OVMF for purposes of
looking at offline VM migration between this environment and Bhyve, and I
thought at first that my VM had locked up. RhodiumToad from Freenode sugges=
ted
that it hadn't locked up, but that it was using a console I wasn't looking =
at,
and he nailed it - I was able to interact on the VM's serial console.

I noted this behaviour on install disks from all of: 11.3-RELEASE,
12.0-RELEASE, 12-STABLE, and 13-CURRENT. Trying the 11.2-RELEASE install di=
sk,
the efifb is used by default.

Something I noted was that 11.2-RELEASE shows the Beastie logo in colour,
whereas the newer installers show it in black and white.

Another slight oddity is that when I opted for a live session from the seri=
al
console, I noticed a functional getty showing up on the efifb, so it seems =
like
the efifb works but simply isn't preferred under 11.3 and newer.

While this behaviour is pretty easy to accomodate, it was surprising, and I
didn't know to look at the serial console at first. I haven't tracked down =
just
why it's happening, but I'd be happy to help explore this.

I've attached an image of the efifb console at the point when the system st=
arts
using the serial console exclusively.
