My firmware does initialize the CT69000 as an environment option that allows what looks like VGA mode consisting of a simple black screen with white text. As per some suggestions I have removed vga_con and added fb_con but received different(worse) results. Without conswitchp = &fb_con I get an exception shortly after the asiliant driver has been initialized. And with conswitchp = &fb_con the system hangs immediately after ppc.md.setup_arch in setup.c.
