Fedora Core 2, full install
X.org 6.8.2, Intel DRI package, Alan's i810_drv.o from April.

If I leave glxgears running, it will eventually (12-20 hrs later) stop updating 
the screen.  It is not hung or dead, as it continues to output frame rate to 
the terminal window and frame rates are not changed.  Multiple copies of 
glxgears running all stop updating at the same time.  I have had this on both 
915G and 915GM h/w.  The X Server itself is fine, I can restart glxgears and it 
will run normally for another x hrs.  I have not tried resizing the glxgears 
window when it is in this state to see if it starts drawing again, I will try 
that next.

Setting LIBGL_DEBUG to verbose does not output any additional info when the 
updates stop happening, and system memory seems to be pretty reasonable.

If there are any logs, configs, etc that are useful, let me know.
