Description Shuang He 2007-08-24 00:45:38 UTC 
on G965 and GM965
occlusion query doesn't return the correct number of smaples that passed depth test
it works for non-dri mode.

I can not reproduce on my GM965 machine with the attached program
Comment 3 Shuang He 2007-09-24 21:39:02 UTC 
on my G965 machine, I got results like following:
number of samples passed depth test = 134758680
should be 900

but in non-DRI mode, it gets:
number of samples passed depth test = 900
should be 900
