I had this problem with an HP DC7700 and ADD2 DVI cards, when I used the 
"i810" driver in xorg.conf.

Changing the driver to "intel" resolved the issues 100%. (I was using 
Fedora 7 Test 3, I'm not sure if the "intel" driver is packaged for 
earlier FC or RHEL versions.) Anyway, you need the "modesetting" intel
