Doesn't the r300g driver already do that ?

Otherwise, I'll probably start working on fleshing out the GSoC clover implementation a bit (implementing built-in math functions and stuff, conformance testing, etc).

For instance, I have an nVidia card at the moment and if I use Nouveau, the temperature gets higher and higher, way above 100?C.
It took me some time to understand why my PC was freezing without any reason...
Since RadeonHD drivers are based on open specs and aren't retro-engineered, are they more stable?
I don't play huge games on my Linux, but I do 3D programming.
For desktop usage and lightweight 3D, there's nothing wrong with the OSS radeon drivers. If you need GL 3/4 features, you might need to use the Catalyst drivers. Both sets of drivers have been quite stable for me in Ubuntu 11.04 and Windows 7 x64.

Why not comparing LLVMpipe to Mesa, to see the real improvements between the two solutions?
Showing the speed of LLVMPipe on its own is useful. We can see that it hits playable framerates in some cases. Putting the hardware results in there helps give you an idea of just how fast LLVMPipe is, e.g. that it's comparable in speed to a low-end hardware renderer (well, with the FOSS drivers, at least). That's actually meaningful. That tells you that LLVMPipe is serious stuff. You now both have solid numbers telling you if LLVMPipe is fast enough for your needs and you have a meaningful reference point for just how fast it is compared to buying an extra piece of GPU hardware.

We already know that Mesa3D is slow and pretty much absolutely useless for anything other than being a reference-test renderer. Comparing the speed of anything to that would be like comparing the land speed of a vehicle to that of an office building.

So, the comparison made in the benchmark is still useless.
