As Jason has already pointed out, it is very likely that your ARM system
does not feature any legacy VGA.  So fb is likely your only option.

Yes, and 592/8 is 74, which is what you are seeing AFAIR.
Try to up your horizontal screen resolution.
If you can get it up to 640, you should be happy.

I used to use 1280 with a 14 pixel wide font.
Gives you 91 chars per line.  And with a bit of stty magic, you get
exactly 88, which is very nice for a Modular Evolution user :-)
