According to linux/Documentation/serial-console.txt, simple specify: 'console=device,options' (device=ttySx, options may include serial port speed, etc.) e.g.: 'console=ttyS1,9600' -or- 'console=ttyS1,9600 console=tty0' to use either serial or the video card.
Of course, to enter this at the LILO prompt, LILO has to be installed with the option to display on the serial port: e.g.: serial = 1,9600n8 (for ttyS1, 9600 baud)
so that you can specify this via the serial port; if not, then you would need a keyboard/video card/monitor to set this :(
OTOH, similiar to your reference to Suns, FreeBSD's initial loader has an option to probe the keyboard (-P)...if a keyboard is found, the video card/keyboard is used; if not, the serial port is used.
