Sorry, I write here from smartphone at the moment, and can't give you detailed linux help.
After you booting into working graphic environment, you can switch back into pure console (console is not terminal :) ) by pressing chord Ctrl+Alt+F1(really from F1 to F6). Log in as tux user or as root. Type your commands. When you finished, type command exit. Anytime you can switch back to graphic by pressing chord Alt+F7 (no need to press Ctrl).
Sometime, on some video cards you can't see anything on console, just plain black screen (like one machine at my work) and I don't know how to cope with it. But hi-res console works fine in my Acer Aspire One AOA150 netbook with Intel integrated video card.
If you like, you can download Terminus console font. I've prepared two packages with it, one with only one size (base) and other package contains all the rest sizes according to your needs. Please, search for 'terminus' packages in cooking repo (use http://pkgs.slitaz.org/ ). After installing fonts, go to your console and type command setfont with parameter: name of font file (sorry, I can't recall details). By the way you can see full list of package's files on http://pkgs.slitaz.org and put these names, one at once, as setfont parameter.
And I want to say, you'll see font changes immediately.
