I managed to diagnose and correct this one myself. Recording here for posterity.
I did a clean install of 10.6.8 on my MacBookPro. After installing the 1.7 driver, the display remained blank (I had previously been using 1.6 b4, I think). I enabled verbose debugging in the DisplayLink Information application and then looked in the Console.
The driver was attempting to load /usr/local/lib/libusb-0-1.4.dylib and failing. Over and over and over and over again. Looking in /usr/local/lib, I found libusb-0.1.4.4.4.dylib but no libusb-0.1.4.dylib.
I symlinked 0.1.4.4.4 to 0.1.4 and then the display started working again.
Looking at a backup of my pre-reinstall drive, I see that that symlink did exist before, though I have no idea how it got created.
