Howto Change Screen Resolution on Ubuntu Server Console

I was browsing the Ubuntu questions the other day when I came across a question about changing the bootup and console screen resolution for Ubuntu server edition. The question was:

Hello,

I am running Ubuntu 6.10 Server Edition on a Toshiba Tecra8000 laptop and I need some help changing the screen resolution from 640X480 to 1024X768. I am also running Xubuntu on a Satellite 4080XCDT and I was able to fairly easily correct the screen resolution by editing xorg.conf. Unfortunately, I noticed that Ubuntu Server Edition does not have an xorg.conf. Is there a similar configuration file that I should edit on the Server Edition? If so, can anyone tell where to find it and some advice on editing it?

Thanks,
Sam

Funnily enough, my server has the same issue - although I only tend to access it via SSH so it's never really been much of a problem. Anyhow, on reading the question I thought I might as well find out more and see if I could find a fix.
