Yes. I'm trying to do that now. I think the BIOS may be telling the
kernel a little white lie. I know that the box will run just fine
if I remove the screen-card after it's up. I also open /dev/null in
../init/main.c if the kernel fails to open an initial console. It
never gets that far, though. Thanks.
