Let us be very clear that we all understand the question you asked.  You did 
NOT ask which drivers support the RENDER extension.  Rather, you specifically 
asked which drivers offer HARDWARE support for the RENDER extension.  Those 
are very different questions.

Almost all of the current crop of drivers support the RENDER extension.  That 
means RENDER-based applications will work correctly.  However, in all but a 
few cases, that support is implemented in high-performance software 
simulations.  The primitives required by RENDER are rather specific, and 
there has not been a lot of time to figure out if the existing hardware (most 
of which was designed long before RENDER was conceived) can be wrapped around 
those requirements.

The i815 is not a terribly sophisticated engine.  I'm not sure it will do 
much better than the simulations.
