I tried that but while this makes things look smoother scrolling in Firefox 
is still slower. When using the radeon driver in 6.8.2 I can open let's say 
"www.linuxtoday.com" drag the scrollbar up and down wildly and the display 
updates almost instantaneously. Using the EXA enabled XOrg version the 
display is updated with a very noticable delay with or without xcompmgr -a.
