I don't know if this is a bug or what? I have had this issue for quite a while, I had the same long time ago on some of my aptosid installations. When I do "init 3" in a terminal window (as root) I will not get to a working terminal screen, I get to a black screen with a blinking line, can't do anything there. I have to do "ctrl+alt+F(x) to come to a working terminal.
