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 console output is nonsense garbled data.  I believe the problem is due to potentially 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?

The graphics card in my systems is an ATI Radeon HD 2600 XT 256 MB.
