Unfortunately there is no native support for the 360 gamepad, and if it didn't make it into FoV / DKS I don't know if I'd hold out much hope for a patch.
Several people have used gamepads in D2:ED, configuring each button manually, without too much complaint (IIRC an action could not be assigned to the right stick, which was used to control the camera on the Xbox, a feature lacking on the PC), though of course there were requests for native support (or at least a few built-in profiles).
Welcome to the forum.
