Well, I wound up upgrading my video card to a Radeon HD5450 w/ 1 GB of RAM, and that worked for a while with the 6 DisplayLink monitors. After rebooting this morning, only the monitors on my video card work. All of the DisplayLink-based monitors are blank...yet still recognized in Windows.
The ZIP file generated from the support tool is here:

When looking at the screenshot in the zip, 1 and 2 are my primary monitors, while the others are driven via DisplayLink.
If you have any questions, or need me to check other things on my system, let me know. I might be able to help debug some of the issues if needed (I'm a software engineer.)
