ATI Mobility FireGL T2
Linux driver - OpenSource
This adapter is supported by recent versions of the 'radeon' driver as found in X.Org and XFree86.
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.
