This morning, like every day, I updated the mesa git repository. And I had the good surprise to see this :
If I'm not too sleepy, this means that mesa 7.9 will be delivered with the r300 gallium 3D dri driver.commit 85a45dcd5d2a6d4ba5ab414d4e7d4285ac998385

Build r300g by default
NOTE: This will go to 7.9 as well.
Note that for testing it since quite some times now, it makes sense.
Have a nice day !
