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 suggested
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 disk,
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 serial
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 starts
using the serial console exclusively.
