103 PrivateBootInfo has fields used by the booter that used to be part of

106 contains the fields the kernel no longer cares about but the booter still
107 uses internally. Some fields (e.g. the video information) remain interesting
108 to the kernel and are thus located in bootArgs although with different field names.
