The correct fix is to implement a fixed function pipeline replacement  
shader and emulate vertex blending with vertex shaders. I have started  
such a replacement pipeline, but have paused it because it did not  
achive the intended results(performance improvements). This was about  
a year ago. Someone rebased it to wine git a few months ago, the  
results are in the wine-devel archies.

Note that my replacement pipeline does not yet implement vertex  
blending, but it is needed to add this emulation on top of it.
