WDDM 1.1 drivers are backward compatible with WDDM 1.0 specification; both 1.0 and 1.1 drivers can be used in Windows Vista.

Can WDDM 1.2 also be used in Windows Vista?

AFAIK it's not completely backwards compatible. However I don't see how the theory helps you, since you've practically tried Win7/8 drivers in Vista and it did not work on your laptop. – Karan Feb 27 '13 at 4:46

AMDs Catalyst drivers also work in Vista, so WDDM1.2 is also backwards compatible:

Compatible Operating Systems

The latest version of the AMD Catalyst software suite is designed to support the following Microsoft Windows platforms:

Windows 8 32-bit version
Windows 8 64-bit version
Windows 7 32-bit version SP1 or higher
Windows 7 64-bit version SP1 or higher

> Windows Vista 32-bit version SP2 or higher Windows Vista 64-bit version SP2 or higher
