    [ChromeOS] Don't initialize VGA Option ROM in normal mode
    
    ChromeOS features two different modes: normal mode and developer mode
    (aka jailbreak mode). In developer mode, we need to display a warning
    screen for security reasons.
    
    However, in normal mode we want to boot blazingly fast. Therefore we
    don't run (VGA) option ROMs, unless we have to print something on the
    screen before the kernel is loaded.
