<pre>I hacked intel_buffer_objects.c::alloc_buffer_object() to pass extra 4096 bytes
to the size given to drm_intel_bo_alloc(). This seems to prevent the failure
also (at least I get 200 test rounds without pixel failures).
I used a hack since this interface (glBufferData()) has no notion of width or
height and therefore preventing cleaner solution.
I would like to note that without knowing the algorithm for the cache handling,
these findings are not yet conclusive - it is still possible that they are once
again hiding the real explanation.</pre>
