Dual Display problem

I am trying to set up my multiple display and have tried to follow several sets of instructions; the problem is that whenever I insert a 'Screen 1' or 'Screen "screen1"' line into the device section(s) of /etc/X11/XF86Config and try to restart KDE I get a "no screens found" error.

I have an ATI radeon 9250 and am using the default drivers found by the installation setup (they work but clone the display), am running Mandriva 2006 Kernal V.2.6.12-12mdksmp and my system doesn't seem to have a /sbin/lspci file.

I've been searching for hours but it's really stumped me, anyone else know how to fix it?

Did you load the xinerama extensions?

You will likely have to post your xorg.conf here. Between [code] tags please...
