You really sure ?

With that you have an compile error with !MODULE && !CONFIG_FRAMEBUFFER_CONSOLE_DETECT_PRIMARY

You are using that code checking !MODULE and you check !map_override with CONFIG_FRAMEBUFFER_CONSOLE_DETECT_PRIMARY

...

#ifndef MODULE
static int __init fb_console_setup(char *this_opt)
{
...
con2fb_map_boot[i] =
(options[j++]-'0') % FB_MAX;
}

map_override = 1; <-- should die here with !CONFIG_FRAMEBUFFER_CONSOLE_DETECT_PRIMARY && !MODULE
}

return 1;
}

...

#endif
