I have tried to install FC2 on a Toshiba Satellite notebook which uses an Intel 852 chip for graphics. The installation went smoothly, the chip was detected and X was configured automatically to use the i810 driver and 3D hardware acceleration. However, whenever I run an OpenGL application there is a square slightly larger than the mouse pointer which is kind of copied from the point the mouse pointer was a few seconds ago and which moves with the mouse pointer. Effectively, this makes it impossible to pick anything with the mouse.
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.

If I turn hardware acceleration off by commenting out the dri module line in xorg.conf everything works as it should be (although without 3D acceleration) and the effect described above does not show up. Unfortunately, the notebook is supposed to be used as a demo machine for an OpenGL application. I have tried the few options available for the i810 driver without making any difference. In particular, enabling a software cursor just turns off hardware acceleration, which is of no use to me. I can't find any description of a problem like this on the net. It seems that people have no problems with the i810 driver.
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.
Has anybody seen such a problem and knows what to do to fix it ?
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!
