That could be it, try to disable KMS or use early KMS. I see this happen once in a while when I boot my desktop pc from a usb drive with arch. Most of the times it boots just fine but every once in a while it will hang at that exact place, "Setting console font ...." but I've never seen a kernel panic or had to clean spaghetti of my screen. I could never figure out exactly what was wrong, starting with a cold boot sometimes it hangs, most of the times it works. -- Mauro Santos
