If you can use the braille display to enter text on the computer the
port on which the braille display lives would be your console. If the
braille display cannot send commands to the computer or text, you have
two different ports and I don't know how that could be accommodated.

I knew it could be fooled into thinking there was a monitor present, but someone informed me that linux also did not necessarily need video hardware either. Unfortunately, the evidence he gave confirmed my own information; that is, editing xorg.conf to use xorg-video-dummy-x86 or similar. This is way ahead of where I am, as there is no xorg yet and we are still at trying to boot a linux USB stick or cd.
