Have you tried Unigine Heaven 4.0?  You need to:

export MESA_GL_VERSION_OVERRIDE=3.2
export MESA_GLSL_VERSION_OVERRIDE=150

but then it works fine, at least on i965, without any workarounds at 
all.  It actually seems to render correctly and everything.  Heaven 3.0 
never did (maybe I need the -ARB_shader_bit_encoding workaround too).

Valley and OilRush still have one bug with blend_func_extended.
