HKEPCreports that, with the latest ForceWare 91.47 drivers, Nvidia has added transparency AA support to GeForce 6-series cards. An anonymous manufacturer told HKEPC it was able was able to enable transparency AA with both a GeForce 6600 GT and a GeForce 6800 GS with the 91.47 ForceWare drivers, but not with the previous 91.31 version. The chaps over at TechReport have installed the 91.47 ForceWare drivers on a system with a GeForce 6800 GS graphics card to test out this claim, and transparency AA is indeed available in both supersampled and multisampled modes in the Nvidia control panel. Gamma-correct antialiasing isn't, though, so Nvidia apparently didn't back-port the GeForce 7 series' whole array of antialiasing features. Nevertheless, a quick game of Half-Life 2 revealed nicely antialiased chain-link fences, so GeForce 6-series card owners have gained an extra image quality feature.
