Forceig a resolution in xorg server

[stan]

I'm (huridelly) building a new machine to replaced my (just failed) main
workstation at work. I have Xorg installed, and when I type X it starts up
OK. KDE, and kdm work also. But, at way too high a resolution. I tried doing
X -configure to generate a config file, but the resultant file contains no
resolution settings.

How can I force X to run in 1280x1024 x 24 bit color mode?
