I'm not sure about the 852 chipset. I have used the 815 and 865G 
chipsets. It sounds like the chipset might be closer to the 865G. If 
this is the case, later versions of X might work without the square.

If it is more like the 815 chipset, there has been work on isolating the 
DRI roblem down to about three specific settings which allow X to work 
in accellerated modes. The bug link below might help. Check the comments 
related to the parameters to disable certi aspects.

Take a look at rh/fedora bugzilla and bugzilla for xorg-x11. There are 
many problems with the i810 code at present within the FC3 development 
branch.

Since you have another chipset that was not mentioned in conversations 
regarding i810 problems, adding your problems encountered into bugzilla 
might help to figure out the cause of the i810 driver failure.

Good Luck!
