I removed the grass blend, it the whole map was covered with the detail texture (grass) with the lightmapped areas still affected. I then tried EntityColor terrain2, 10,10,10 and again the only area affected was the area used by the lightmap, as if it seems to only address these areas. The "insaner" multitexturing demo is the same way, you cant change the ambient lighting at all so im guessing its the same problem.
