I would try something with timing and detection of a sound card in addition to the monitor. Ubuntu systems use ks.cfg files Debian uses preseed files. I saved from several years ago a ks.cfg file in braille that was offered by a website in England and believe it or not actually got ubuntu in an earlier version talking after an install from that website file. I don't know if a preseed file is more desireable than a kickstart file and I think I can find the braille notes in my pile of braille papers here.
