Deploying Dell drivers with Altiris Deployment Solution 7.5?

Hi, I am a new poster in here and have really tried to do my homework on this before posting. Sorry if I missed anything. Here goes:

We are currently implementing Altiris Deployment Solution 7.5 with just one base Windows 7 image. We then wish to add drivers by scripted installation from a network share as part of the deployment job. For Hewlett-Packard and Lenovo computers this is an easy job, using SSM and Thinstaller.

Not so much for Dell. We have tried using Dell Repository Manager in conjunction with Dell Client System Update = no dice.

DRM works reasonably well with DCSU on a single client using the GUI, but apparently the built-in command line client cannot do the same, refusing to detect missing drivers and install them. This seems inordinately silly.

Is there a better way that does NOT involve buying add-ons to Altiris just for this simple purpose? How has everyone been solving the issue of automating driver installation to newly imaged Dell systems with Altiris?
