Bug#604101: installation-reports: Broken textmode installer
Same issue applies on IBM x236 server, was about to shelve debian and start picking a new distro until I found this report. It never once occurred to me that when choosing a text based install the installer would attempt to use a graphic mode to do it in. The seems like broken administration of the installer, rather than a technical mal-function. The whole purpose of text mode imo is to give a generic works on any device environment as a fail safe when graphical install fails or is not feasible. No vga mode should ever be set for this option, nor anything that even considers a frame buffer. The issue is very easy to resolve once understood, but this is a never should have happened in the first place error to rival "No keyboard detected, Press F1 to continue".
