Great news everyone! I have found Vista64 compatible drivers for our DWA-142's! The adapter uses Marvell's TOPDOG chipset, so I was able to find generic drivers for it. The driver date is January 19 2007, and the version is 1.0.0.4.
The 453KB download can be found here:

Not the ideal solution, but I am typing this message to you using the driver, so I can verify that it works. Regardless, this should at least get you guys back on the web until D-link gets off their @$$es and releases official drivers.
Man, it pi$$es me off to have to track down my own driver for a new adapter like this. If one works, but hasn't been thoroughly tested, mark it as a BETA. At least then people would be able to use their adapters.
