Right, seems like I did not think this through. Earlier I thought we 
could simply turn it on for all drivers that support ARB_timer_query 
(and robustness) but seems not all the drivers do so we need to toggle 
it on separately. I will need to update this one and add a separate 
patch to toggle it on in the i965 driver.
