This probably is not a solution, but did you see if you could adjust 
"gnome-display-properties". There is a pull-down you can adjust  
vertical refresh. I am thinking that one is interacting with the X settings.

Regarding the Intel 865, I have an 856G away at work. I run 1280x1024 
and note no problem. I believe gnome-display-properties shows 75HZ for 
my settings. I can check out this tomorrow to verify vertical settings. 
I have th latest version released into updates for FC4 installed.
