Screen rotation without X.org

Is it possible to rotate the CLI bare CLI screen? I'm talking about a system with no X.org. I'm using a 1600x1200 screen and would like to get more vertical screen estate by rotating the screen into portrait mode.

I'm currently running Slackware 13.0 x64 on a Intel atom board (D945GCLF2D).

Thanks in advance for all the help.

Welcome to the forums!

Maybe the fbcon=rotate option would work for you with the framebuffer console:

I've never used it so can't offer up any specific help with it, but look at line #126 for the details:
