Ping tpearson about this.
Also ping him about the fact that there isn't actually an option to
enable or disable native graphics initialization, but that the option
MAINBOARD_HAS_NATIVE_VGA_INIT_TEXTMODECFG is in fact available and set to Y in the
Kconfig file. I think this is probably since there isn't even an option
ROM available for the machine, so it's pointless to offer the setting.
