+- Added xorg-x11-6.8.2-redhat-nv-disable-s2scopy-on-geforce-6x00.patch to
+  work around "nv" driver bug, by disabling ScreenToScreenCopy on certain
+  GeForce 6200/6800/6800 cards which the problem has been reported on,
+  until there is a real upstream fix, as the current CVS head driver we
+  now have, still suffers from the problem.  We may also need to blacklist
+  other cards as new reports come in.  (#157715)
+
 * Mon Jul  4 2005 Mike A. Harris <mharris redhat com> 6.8.2-41
 - Added xorg-x11-6.8.2-nv-driver-CVSHEAD-6.8.99.13.patch backport of CVS head
   nv driver to track the latest bug fixes and hardware support.  Hopefully
