Ok so what actually happens on the display when you start the graphical console? do yuo get any display? black screen?
It doesn't appear to be using the i810 module at all (defaulting to VESA instead)
It's complaining about the following modules, so try:-
yum install xorg-x11-drv-vga xorg-x11-drv-fbdev
P.S for the sake of keeping posts lengths down only post the errors please!
grep -e EE -e WW /var/log/Xorg.0.log
