XGL/Beryl/Compiz with Xorg 7.2

[Tom Grove]

Has anyone tried installing and using any of the above after 7.2 was 
committed?  I tried all weekend and just get poor results.  In XFCE and 
Gnome performance is unusably slow.  I have a dual-core cpu with 1GB of 
memory and a 256MB NVidia video card.  It certainly shouldn't be slow 
because of hardware.  I just can't find much documentation because the 
7.2 port is so new.  Any help is much appreciated.  Thanks.
