Newbie & Debian 3.0 & GeForce4 MX 440

[Aedificator]

Recently i've installed DEbian 3.0 on my PC (512 mb ram, P4 1.6 GHz, GF4 MX 440).   When trying to run X i get the "no screens found" error. No matter which driver (svga, nv) i choose during the installation process the Xserver fails.   My system worked fine under Red Hat 7.3 so it's a Debian thing.   Can anyone help me?   Zee
