Back in June the initial GMA 4-Series support
was added to their open-source stack for mode-setting, 2D, 3D, and video acceleration along with DisplayPort and HDMI connector support
with these new Intel integrated graphics processors. Following that we had published Intel GMA X4500 (G45) benchmarks
under Linux using the latest code at the time. The GMA X4500 worked out fairly well, but Intel has since introduced the G41 Chipset.
The Intel G41 is a slightly stripped down version of the G45 but still is part of their 4-Series GMA graphics. As of today, the G41 is now supported via their open-source Mesa/X.Org code too. The commits can be found in their respective git repositories, but they're just trivial with the addition of the new PCI ID.
