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.
