204w ago - The new Mesa 7.5 has been released recently.
The interesting thing about it is that it is first release to contain Gallium3D architecture for "OS-independent and API-independent 3D drivers" which in turn contains drivers for various devices such as:
• softpipe - a software/reference driver
• i915 - Intel 915/945 driver
• Cell - IBM/Sony/Toshiba Cell processor driver • nouveau (for NVIDIA GPUs) and R300 for (AMD/ATI R300)
This in fact will bring accelerated 3D graphics to PS3 where the graphics processing won't be done by RSX but by employing SPUs. This would vastly enhance usability of Linux running on PS3 by providing one of the things it's lacking now...

I wonder how soon the different linux distributions will get this in their repositories. I haven't played around with Linux on the PS3 recently, but with wireless controllers working and now 3D acceleration it may be time to get it setup again with emulators to test it out.
What I would like to know is how many SPUs will this utilize, and since there are multiple SPUs in the PS3 couldn't some be used for 3d acceleration and others for CPU power? Or maybe I don't have a good understanding of how they are utilized when booted in linux?
