Enhancing cdboot [patch for review]

[Jonathan McKeown]

While you're enhancing cdboot anyway, can I ask how complicated it would be to 
make cdboot serial-console capable? (I'm not a C programmer, I'm a sysadmin - 
but I'd be prepared to try and look at this myself if no-one else is 
interested).

As it stands, the only way I've found to do a serial-console CD-based 
installation is by enabling the serial console in /boot/loader.conf, by which 
time you've already missed several useful points, particularly the entry to 
BIOS settings (if you have a serial-capable BIOS).
