I'm going to add a comment to help people Googling this issue. The ATI Mobility M7740 chip, which was one option for the Dell M6500 Mobile Precision laptop, is apparently considered a 4000-series chip, and so is a victim of this AMD policy.
One of the supposed justifications for over-priced "workstation-class" graphics chips was top-notch vendor support. By so cutting short its support of this chip, AMD has demonstrated that they can't be trusted to support workstation-level users.
Unless something radically changes, I can't see buy AMD for my Linux laptops / desktops anymore. What a shame.
