Excerpt from ARB_occlusion_query.txt: An implementation can either set QUERY_COUNTER_BITS_ARB to the value 0, or to some number greater than or equal to n. If an implementation returns 0 for QUERY_COUNTER_BITS_ARB, then the occlusion queries will always return that zero samples passed the occlusion test, and so an application should not use occlusion queries on that implementation. This looks more sane for drivers wanting desktop gl 1.5 without real hw support then just faking it.
