This commit also breaks up opengl32 winetest: http://www.reactos.org/testman/compare.php?ids=7618,7621,7622
I guess you will see an entirely different test result if you only run the opengl32 test right after booting ReactOS.
IMO these 'floating' test results show that there are bugs buried deep in the system. Memory corruptions come to my mind...
