okay, so for starters, I stopped being stupid and looked at ALL the Xorg 
threads I could find, not just ones that seemed to pertain to my 
problem. I combined a few ideas and seem to have fixed my issue for now. 
I grabbed all of the 6.8.1 packages for xorg, and did a 'rpm -Uvh 
--oldpackage' on them all. Then, I ran 'yum update xorg-x11-base' and 
installed that and it's "dependancies" which consisted of xorg-x11-xfs 
and xorg-x11-libs. Yum didn't update any of the other packages (even 
though I had replaced everything with v6.8.1, and all the other packages 
showed up when I did a yum check-update) and suddenly, vnc works 
perfectly. I have yet to check the system on boot, because I can't 
reboot it again until tomorrow morning, but for now I'm satisfied with 
vnc working again.

I'd like to once again thank Tony and N. Emile, as well as Paul Howarth 
who provided the information for manually downgrading packages with the 
rpm command in another thread.
