How to get Lilliput USB monitor working?

Okay, I just got a Lilliput 7" USB Monitor:

_{(source: thinkgeek.com)}

Unfortunately, I am having some trouble getting it to work in Ubuntu.

It is a DisplayLink device, so it should work in Ubuntu.

Here is the output of lsusb:

...
Bus 002 Device 007: ID 17e9:02a9 Newnham Research
...

I modified my xorg.conf file to accommodate the device.

All I get is a green screen.

Any tips or advice would be appreciated!

Update: I discovered that X11 was having trouble finding the displaylink_drv.so module, so I fixed that. Then my XServer completely crashed. (Segmentation fault, I believe.)

Now I'm really confused.
