Hmm, not sure what you mean -
http://www.displaylink.com/downloads/ubuntu is indeed where you can find the latest version, and also previous ones.
There is no binary kernel driver in the solution for Ubuntu DisplayLink proposed. All the source code is on GitHub and we're accepting contributions.
udl (current DRM compatible module) and udlfb (legacy fb device) are modules for older DL chip families (DL-1xx), these won't work with USB3.0-era devices.
