Both Nvidia and ATI are working on Vista drivers, and once this operating system is out, people will be able to see that last year's decision by ATI to start using frameworks was not a bad idea after all.The final version of Windows Vista will feature DirectX 10 but it's possible that one of the upcoming versions will have DirectX 9.0L, which adds Shader Model 4.0 (SM4) support.
All Vista drivers will need frameworks, as this is something what Microsoft demanded, it was not a choice, it was an order.
