looks really good to me!

Reviewed-by: Ingo Molnar <mingo@xxxxxxx>

small nit:

+       vc->vc_color = printk_color;
+       update_attr(vc);

that should be in a set_vc_color() function and the new code should do:

+	set_vc_color(vc, vc->vc_color);

(and same at the other places that call update_attr() as well)

feature request: would be interesting to have a color table (defined in 
the .config) dependent on message loglevel. That way KERN_CRIT messages 
could be red, KERN_INFO ones white, etc.
