Well as of today Dell has updated some driver files for SCCM.
The Dell Optiplex 760 has a new driver pack (9/4/2009) under Systems Management
What is even better is that some of the models are showing a pack for System Center Configuration Manager. This should make it easier to load and inject drivers into the image. I will see if I can run down the model list and list a few here for you to see.
