He's using console=comconsole (serial boot).
When that is the case, loader_color is automatically set to NO.
There's no reason to set both loader_color=NO and console=
comconsole. The code that does this is here:
http://svnweb.freebsd.org/base/release/9.2.0/sys/boot/forth/color.4th?revision=255898&view=markup
Line 48 within the loader_color? function:
boot_serial? if FALSE else TRUE then
As for answering the quandary of where the keyboard is polled
during the timeout countdown, that's the getkey function in here:
http://svnweb.freebsd.org/base/release/9.2.0/sys/boot/forth/menu.4th?revision=255898&view=markup
