It is not that bad.  If a bootloader is configued to use autodetection
so that it is shown at best video mode, then it should have advertised
key sequences to default to known video modes, with at least a 480p 'safe'

Second stage kerenls can be booted with a videomode appended on the
command line, and all kboot.conf's should have a 480p 'safe' mode
