I don't ever recall seeing anything on the serial ports when trying to use
ARC without a video card.  The LED on the motherboard just goes berzerk and
the machine totally fails early on in POST.

You CAN use ARC on a serial console however, which is what I do.  You just
change the CONSOLEIN and CONSOLEOUT environment variables.  But you do need
the video card and keyboard to do this, and you must leave them connected
in order for ARC to pass POST.
