Okay yes so then it means we could go up to 255 lines, too, right? > > I tried specifying nothing and I got a 135 lines per 480 column screen > > which was actually not usable, for reasons I am not able to explain. > > What do you mean by "specifying nothing"? At least on Debian, there is a file called /etc/default/console-setup in wchich you can define two shell variables, SCREEN_WIDTH and #SCREEN_HEIGHT. I meant I left these two undefined and that's how I obtained the 135 lines by 480 columns, this second number actually making not much sense if I understood you correctly.
