At this time, both TERMINAL_NORM_ATTR and TERMINAL_KERN_ATTR are set based from teken.fg_color and teken.bg_color, to get  consistent console while transitioning from loader to kernel.

This one is option to override RGB values for color identified by colornum. FreeBSD console is only supporting colors 0-7 there (see sys/terminal.h). However, this feature is only available for framebuffer console (not vga graphics or text).
