uga output

First of all, I believe my problem is related to bug #202730.

I am trying to boot 10.3-RELEASE on a Mac Pro 2008. I boot the mac and hold
down the ALT key to choose the memstick (flashed with
FreeBSD-10.3-RELEASE-amd64-uefi-memstick.img).  I see the FreeBSD text boot
loader and proceed to let the system boot in multi-user mode to get to the
installer.

The problem I encounter is that once the kernel is loaded, the kernel conso=
le
output is nonsense garbled data.  I believe the problem is due to potential=
ly
incorrect graphics settings?

Sorry I do not know all the correct terminology to describe what I'm seeing.

After reading bug #202730, I ran the `uga` command at the boot prompt.  See=
 the
attached image for the output.  Perhaps the errors can help diagnose the
problem?
