Unfortunately, an apparently knowledgeable compiz person said: This is a limitation of DRI, DRI2 should fix this, and should hopefully be in most drivers by Xorg 7.5(maybe 7.6), nvidia has there on implementation, that's why it works on it http://forum.compiz-fusion.org/showthread.php?t=8462 And poking around, http://www.phoronix.com/scan.php?page=news_item&px=NjYzNw "sometime in 2009" is the closest I could get to finding an expected date when this would be available ...
