Yeah, it's a lying Dothan. I did find a hacked up version of a driver that seems to work for simple HW accel. In Vista, you could apparently manually force it to use the built-in Mobility Radeon 9000 driver, but 7 purged out the pre-HD Mobile Radeons.

I don't trust ThinkWiki often, as most of it is written for the Linux user of 2006.
