ATI Mobility FireGL T2
Linux driver - OpenSource
This adapter is supported by recent versions of the radeon driver as found in X.Org.
The Xorg 6.8.1 driver works (including suspend), but dualscreen is not working on some models. The Xorg 6.8.2 release has quite a few fixes for the driver, allowing dualscreen for example on a T42p.
The SVideo port should be supported by the current Xorg radeon driver.
Please read How to get TV-Out working on ATI graphic cards on how to set it up.
Linux driver - Proprietary
The fglrx driver adds 3D acceleration.
