That's just the console driver.  You want to affect the console device
selection logic.  There seems to be more than one way to do this.  My
favorite is to create a file named /boot.config with it's only contents
being "-P".  This sets you up to use the graphics screen if the kernel
detects a keyboard is plugged in, otherwise it uses the serial port.

See boot(8) for details, in particular the section named Boot flags.
