I used yum in FC3 to upgrade after I did the clean installation, so I do 
have a log. The problem there is the list is rather extensive, as a 
stock-from-the-ISO installation is now rather out of date. I looked 
through the entire list, but unfortunately nothing really jumps out at 
me as a likely suspect. I wouldn't call myself a linux expert, so I'll 
attach the log and see if anyone can spot something that I didn't.
