I discovered that quite by accident when I ran <chown root:root
/usr/bin/Xorg>. I had thought previously that Xorg needed to be only
suid. I learned something.
Now "X" starts as root, but not as me. I get:

This occurs, as I said, when I'm logged in as me and not root. I do not
know what generates the "xf86OpenConsole" messages. Again it appears to
be permissions, but I don't know where to look unless, perhaps, I need
to change the ownership and/or permissions of the xf86 drivers that I
installed--evdev, synaptics, fbdev and vesa.
I added myself to the tty group to get as far as the above error
message. As me, the Xorg server couldn't access /dev/tty until I did.

I thought that the symlink question might have been a crazy one when I
asked it. At the time, my finding was cycling through all "possible and
obvious" permission options.
Thanks again, Armin.
