Start the install. flip to another console to see why its going wrong, flip back to the first console after its done at lot of the start up and you get mangled dialog boxes with the wrong font stuff. I think anaconda is loading the font into tty0 (current) not tty1 ?
you switched really early, right? Probably the font got loaded on VT1 while you were on VT3. We're loading to the right fd (stdout)
