 Mikhail, ati.patch.3 is patch for *2D* driver to enable DRI.
 
 However, at the moment, there is *NO* 3d driver for R300 cards except the 
 binary only ati one.
 
 So yes, the DRI will be enabled. But, NO, you will not get 3d rendering 
 because of this patch, only r300_demo will work.
 
                          best
