Not sure if this will help or not but I noticed a higher than usual 
(100%) cpu load after a recent upgrade and was able to fix it by adding 
Option "UseEvents" "True" to the screen section in my xorg.conf. This 
was with a setup using a composite connection to the tv. My other 
systems which use DVI output did not suffer the same problem.
